Central limit theorem Imagine that you are doing an exhaustive study on the children in all of the elementary schools in your school district. You are particularly interested in how much time children spend doing active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent doing active play on weekends is μ = 87.85, with a standard deviation of σ = 118.1. You select a random sample of 25 children of elementary school age in this same school district. In this sample, you find that the average number of minutes the children spend doing active play on weekends is M = 79.07, with a standard deviation of s = 129.91.
The difference between M and 1.1 is due to the :_______
Answer:
Sampling error
Step-by-step explanation:
The answer is sampling error.
The sampling error occurs when the sample does not represent the full population and the result from the sample is not a representation of the results from full sample.
From information given
Population mean = 87.85
Population standard deviation = 118.1
n = 25
Sample mean = 79.07
Sample standard deviation = 129.91
118.2/√25
= 23.62
The standard deviation of the distribution is what is referred to as standard error of m = 23.62

I’ll give Brainly! 1. What is the product of a number and its multiplicative inverse?
2. Find the multiplicative inverse of each number.
A. 5/3
B. −1/5
C. −3
Answer:
The multiplicative inverse of a number is a number, when multiplied by the original number, gives the product as 1
The easiest way to find the multiplicative inverse of a number is to get the reciprocal of the number, and that is also the multiplicative inverse of the number
1. As mentioned above, the product of a number and its multiplicative inverse is 1
2.
a) The multiplicative inverse of 5/3 is also the reciprocal of the same number
Multiplicative inverse: 3/5
b) The multiplicative inverse of -1/5 is also the reciprocal of the same number
Multiplicative inverse: -5/1
c) The multiplicative inverse of -3 can also be written as the reciprocal of the same number
Multiplicative inverse: -1/3

A coffee shop sells a ceramic refill mug for $8.95. Each refill costs $1.50. Last month Rose spent $26.95 on a mug and refills. How many refills did she buy?
Operation: Two - step equations
Answer:
12 refills
Step-by-step explanation:
26.95 = 8.95 + 1.50x
26.95 - 8.95 = 1.50x
18 = 1.50x
18 ÷ 1.50 = x
12 = x
Given h(2)
–5x – 1, solve for x when h(x) = -6.
Answer:
x = 1
Step-by-step explanation:
Step 1: Define
h(x) = -5x - 1
h(x) = -6
Step 2: Substitute and Evaluate
-6 = -5x - 1
-5 = -5x
x = 1
On the planet of Mercury, 4-year-olds average 3 hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.4 hours and the amount of time spent alone is normally distributed. We randomly survey one Mercurian 4-year-old living in a rural area. We are interested in the amount of time X the child spends alone per day. (Source: San Jose Mercury News) Round all answers to 4 decimal places where possible.
Required:
a. What is the distribution of X?
b. Find the probability that the child spends less than 1.4 hours per day unsupervised.
c. What percent of the children spend over 3.5 hours per day unsupervised.
Answer:
a
The distribution of X is normal
b
[tex]P(X < 1.4) = 0.12654[/tex]
c
[tex]P(X > 3.5) = 0.36051[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 3 \ hours[/tex]
The standard deviation is [tex]\sigma = 1.4 \ hours[/tex]
Generally given from the question that the amount of time spent alone by the population size is normally distributed then then the distribution of X (i.e the amount of time spent by the sample size (the one Mercurian)) will be normally distributed
Generally the probability that the child spend less than one hour in a day is mathematically represented as
[tex]P(X < 1.4) = P(\frac{X - \mu}{\sigma} < \frac{1.4 - \mu}{\sigma} )[/tex]
Here [tex]\frac{X - \mu}{\sigma } = Z (The\ standardized\ value\ of\ X)[/tex]
So
[tex]P(X < 1.4) = P(Z < \frac{1.4 - 3.0}{1.4} )[/tex]
[tex]P(X < 1.4) = P(Z < -1.1429 )[/tex]
From the z-table the value of
[tex]P(Z < -1.1429 )=0.12654[/tex]
So [tex]P(X < 1.4) = 0.12654[/tex]
Generally the percentage of children that spends over 3.5 hours unsupervised is mathematically represented as
[tex]P(X > 3.5) = P(\frac{X - \mu}{\sigma} > \frac{3.5 - \mu}{\sigma} )[/tex]
[tex]P(X > 3.5) = P(Z > \frac{3.5 - 3.0}{1.4} )[/tex]
[tex]P(X > 3.5) = P(Z > 0.3571 )[/tex]
From the z-table the value of
[tex]P(Z >0.3571 )=0.36051[/tex]
So [tex]P(X > 3.5) = 0.36051[/tex]

Nora drew non-square rectangle. then she drew the length of each side from end to end to make a line segment that represent the perimeter. write an equation that represents the perimeter of the model shown
Answer:
2L+2W=P, where L is the length, W is the width, and P is the perimeter.
Step-by-step explanation:
To find the perimeter of a rectangle, you add the length twice and the width twice, which translates to W+W+L+L, or 2L+2W.
Expression for the perimeter → 2(l + w)
Given in the question,
Tow pairs of the segments with the length 'w' and 'l'Expression that defines the perimeter of a rectangle,
Perimeter = 2(Length + Width)
From the figure attached,
Perimeter of the rectangle = 2(l + w)
Therefore, expression for the perimeter will be 2(l + w).

Suppose that Estella was making lemonade alongside three friends and decides to invite an additional friend to help. How many additional glasses of lemonade can Estella and her four friends produce?
After inviting an additional friend to help, Estella and her friends can make a total of 5 glasses of lemonade, which is an additional 1 glass.
Suppose Estella was making lemonade alongside three friends and decides to invite an additional friend to help.
The number of additional glasses of lemonade Estella and her four friends can produce will depend on several factors, such as the recipe's ingredients, the size of the glasses, and the capacity of the lemonade container.
Suppose each person can make a glass of lemonade using half a lemon, a tablespoon of sugar, and a cup of water.
To make five glasses of lemonade, Estella and her friends would need 2.5 lemons, 5 tablespoons of sugar, and 5 cups of water.
Suppose Estella has enough lemons, sugar, and water to make 20 glasses of lemonade, and each glass is eight ounces.
After inviting her friend to help, Estella and her four friends can make a total of 25 glasses of lemonade, which is an additional 5 glasses.If each person makes a glass of lemonade that is six ounces in size, Estella and her friends can produce 30 glasses of lemonade.
With an additional friend, they can make 35 glasses of lemonade, which is an additional 5 glasses.Suppose Estella's recipe only produces one glass of lemonade per person.

What are the coordinates of the graphed point? An x y coordinate system. The x axis extends from negative 5 to 5, and y axis extends from negative 5 to 5, with whole numbers marked on the grid. A point is marked 3 units to the left of the y axis and 2.5 units up from the x axis. CLEAR CHECK (2.5, −3) 2.5 , (−3, −2.5) -3 , (3, −2.5) 3 , (−3, 2.5)
The Coordinates of the graphed point are (−3, 2.5).
The coordinates of the graphed point, based on the given description, are (−3, 2.5).
The x-coordinate represents the horizontal position of the point, and it is described as being 3 units to the left of the y-axis. Since the y-axis is the vertical line passing through x = 0, moving 3 units to the left means the x-coordinate is −3.
The y-coordinate represents the vertical position of the point, and it is described as being 2.5 units up from the x-axis. Since the x-axis is the horizontal line passing through y = 0, moving 2.5 units up means the y-coordinate is 2.5.
Therefore, the coordinates of the graphed point are (−3, 2.5).
