A track and field coach wants to analyze the effect of sports drinks on the performance of his athletes. He decides to test three brands: Powerade, Gatorade and Vitaminwater. He will have each of the athletes complete a 400 meter run and record their times. Which of the following represents a confounding variable?
a. He decides to give all male athletes Gatorade and the female athletes eitherPowerade or Vitaminwater.
b. Yes gender would be confounded with sports drink since we cannotdistinguish their effects from each other.
c. He allows each athlete to choose their favorite drink from a cooler.
d. He has some of the athletes drink the sports drink two hours beforerunning,others one hour before running, and the rest 30 minutes beforerunning.
e. He has some of the athletes drink Gatorade two hours before running, othersdrink Powerade one hour before running, and the rest Vitaminwater half anhour before running.
e. Yes sports drink would be confounded with timing of the drink, since wecould not distinguish their effects from each other.
Answers
Answer:
A, D,
A.) He decides to give all male athletes Gatorade and the female athletes eitherPowerade or Vitaminwater.
D.) He has some of the athletes drink the sports drink two hours beforerunning,others one hour before running, and the rest 30 minutes beforerunning.
Step-by-step explanation:
Confounding variables could be described as variables which introduces elements that causes unwanted relationship between measured variables in data. Such that observed relationship is actually not as a result of the independent variable.
The confounding variables in the options chosen are gender and timing of the consumption and when the athletes eventually ran.
As for gender, male athletes are expected to put up a better running speed and energy than women and Hence would finish the rate faster based on these fact. Hence, it will be wrong to conclude that Gatorade has Better effect on performance.
As for timing, those who run shortly after taking an energy drink are more likely to be boosted that those who take much later and this the effect may not necessarily be in the type of energy drink consumed.
Confounding variables are the variables which are not related to the experiment.
Gender would be confounded with sports drink since we cannot distinguish their effects from each other.Sports drink would be confounded with timing of the drink, since we could not distinguish their effects from each other.What is confounding variable?Confounding variables are the variables which are not related to the experiment. Confounding variables provides the affects the useless results and affects the experiment.
Given information-
The total number of meters the athletes runs is 400 meters.
The sports drink given to athletes are Powerade, Gatorade and Vitamin water.
The given options are,
a) He decides to give all male athletes Gatorade and the female athletes either Powerade or Vitaminwater- As the male atheletes likely have more power and energy to run than the female athletes. Thus this can ruin the experiment. b) Yes gender would be confounded with sports drink since we cannot distinguish their effects from each other.c) He allows each athlete to choose their favorite drink from a cooler- To choose favorite drink does not affect the experiment.d. He has some of the athletes drink the sports drink two hours before running, others one hour before running, and the rest 30 minutes before running- The athletes who have taken drink just before the race, have more energy. Thus it is a confounding variable.e. He has some of the athletes drink Gatorade two hours before running, others drink Powerade one hour before running, and the rest Vitamin water half an hour before running-similar effect as the in the above case with the timing for this option.f). Yes sports drink would be confounded with timing of the drink, since we could not distinguish their effects from each other.Hence,
Gender would be confounded with sports drink since we cannot distinguish their effects from each other.Sports drink would be confounded with timing of the drink, since we could not distinguish their effects from each other.learn more about the confounding variable here;

Find the range of the function f(x) = 3x - 8
if the domain is {-4, 2, 7).
Answers
Answer:
f(-4)=3(-4)-8
f(-4)=-12-8
f(-4)=-20
f(2)=3(2)-8
f(2)=6-8
f(2)=-2
f(7)=3(7)-8
f(7)=21-8
f(7)=13
R=(-20, -2, 13)
The range of the function when f(x) = 3x - 8 and the domain is {-4, 2, 7) is (-20, -2, 13).
Calculation of the range:Since
f(-4)=3(-4)-8
f(-4)=-12-8
f(-4)=-20
Now
f(2)=3(2)-8
f(2)=6-8
f(2)=-2
Now
f(7)=3(7)-8
f(7)=21-8
f(7)=13
So,
R=(-20, -2, 13)
hence, The range of the function when f(x) = 3x - 8 and the domain is {-4, 2, 7) is (-20, -2, 13).

Olivia’s passcode has four digits. The second digit from the left is three times the first (left-most) digit. The number formed by the last (right-most) two digits is three times the second digit from the left. The sum of the digits is 21. What is Olivia’s passcode?
Answers
Answer:
3927
Step-by-step explanation:
How I did this was just trial and error. 1315 doesn’t work as it only adds up to 10. Lets try 2618. It still only adds up to 17. Let’s try 3927. It Works! Many get confused as they assume “The number formed by the last (right-most) two digits is three times the second digit from the left.” As adding up the last two digits. However, getting 21 is not possible considering the circumstances If you add the last two digits as a multiple. If you have 1234, the 3” and 4” aren’t separate numbers. The 3” and 4” is 34” not 3+4.
3+9=12. 12+2=14. 14+7=21.
Using the hit and trial method and the given condition Olivia's passcode can be determined. Olivia's passcode is 3927.
Given :
Olivia has four digits passcode.
The following steps can be used in order to determine Olivia’s passcode:
Step 1 - Let Olivia's passcode be 'wxyz'.
Step 2 - The sum of all the digits is given by the equation:
w + x + y + z = 21
Step 3 - The linear equation that represents the situation "The second digit from the left is three times the first (left-most) digit" is given by:
x = 3w
Step 4 - Now, use the hit and trial method first put (w = 1) and check all the given conditions. If w = 1 then x = 3 and but the third condition that is the last (right-most) two digits is three times the second digit from the left is not satisfied.
Step 5 - Now, put (w = 3) and check all the given conditions. If w = 3 then x = 9 and the last two digits become 2 and 7. And the sum of all the digits is equal to 21.
Step 6 - From the above steps, it can be concluded that the passcode is 3927.

Answers
This question is incomplete, the complete question is;
The owners of Spiffy Lube want to offer their customers a 10-minute guarantee on their standard oil change service. If the oil change takes longer than 10 minutes to complete, the customers is given a coupon for a free oil change at the next visit. Based on past history, the owners believe that the timer required to complete an oil change has a normal distribution with a mean of 8.6 minutes and a standard deviation of 1.2 minutes.
Suppose management could improve the process by reducing the mean time required for an oil change (but keeping the standard deviation the same). How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average
Answer:
Required change in the mean service time is 7.8988
Step-by-step explanation:
Given the data in the question;
How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average
let mean = μ
p( x > 10 ) ≤ (1/25)
p( x > 10 ) ≤ 0.4
p( x-μ / 1.2 > 10-μ / 1.2 ) ≤ 0.4
(10-μ / 1.2 ) ≤ 0.4
(10-μ / 1.2 ) ≥ [tex]q_{norm}[/tex] ( 0.96 )
(10-μ / 1.2 ≥ 1.751
10-μ = ≥ 1.751 × 1.2
10-μ ≤ 2.1012
μ ≤ 10 - 2.1012
μ ≤ 7.8988
