The correct answer is Option B. Parameters are defined as a group of numerical characteristics of a population.
Parameters are generally the numbers or values that represent the whole population's numerical characteristics. There is a difference between Statistics and Parameters.
Statistics is generally defined as the numerical characteristics of a sample. For example, a sample of standard mean or a sample of standard deviation is an example of statistics.
Parameters are the numerical representation of the characteristics of a population. For example, Population mean or Population standard deviation are examples of Parameters. These represent the data or the characteristics of the population in numerical.

if the probability of a is 0.45 and the probability of the intersection of a and b is 0.15, then the probability that b will occur given that a has occurred is:
The probability that b will occur given that a has occurred is 2/5 as the probability of a is 0.45 and the probability of the intersection of a and b is 0.15.
What is probability?It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. For instance, the theoretical chance of getting a head when tossing a coin is 12. Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.
Here,
P(A)=0.45
P(A∩B)=0.15
P(A∪B)=1
P(B)=1-(0.45+0.15)
=1-0.60
=0.4
=2/5
With a probability of 0.45 and a and b's intersection having a 0.15 probability each, the likelihood that b will happen given that a has happened is 2/5.

the distribution of results from a cholesterol test has a mean of 180 and a standard deviation of 20. a sample size of 40 is drawn randomly. find the probability that the sum of the 40 values is greater than 7,450. (round your answer to four decimal places.)
The probability that the sum of the 40 values is greater than 7,450 is 0.0239
Define Normal Distribution.
A normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.Formula of Normal Distribution isZ = (x - μ ) / (σ / √n )
We have given following info,
mean μ = 180
Standard deviation σ = 20
n = 40
σ(mean of x) = σ / √ n
= 20 / √40
= 3.16
Sample average (mean of x) = 7450 / 40
= 186.25
P(x > 186.25) = 1 - P(x < 186.25)
= 1 - P( (x - μ ) / σ(mean of x) ) < ( [186.25 - 180] / 3.16) )
= 1 - P( Z < 1.98)
Using Normal distribution table,
= 1 - 0.9761
P(x > 186.25) = 0.0239
Therefore,the probability that the sum of the 40 values is greater than 7,450 is 0.0239

The total sum of money is 77 dollars .
Let the total sum of money be x .
⇒ Aziz's share = 4x / 11
Ahmad's share = 7x / 11
Given : Aziz received 21 dollars less than Ahmad
⇒ 4x / 11 = ( 7x / 11 ) - 21
Solving the above linear equation in one variable ,
( 7x - 4x ) / 11 = 21 ( taking like terms together )
3x = 21 * 11
x = 7 * 11
x = 77
Aziz's share = ( 4 / 11 ) * 77 = 28
Ahmad's share = ( 7 / 11 ) * 77 = 49
Total Sum of money = 28 + 49 = 77 dollars .
