Assume that a national fitness study reports that 10%10% of millenials exercise daily. suppose that a researcher surveys a random sample of 250250 millenials regarding their daily exercise habits. assume that is a binomial random variable that represents the number of millenials in the sample who exercise daily. compute the mean μ and standard deviation σ of the sampling distribution of . report μ as a whole number and σ as a decimal precise to two decimal places.

The mean μ and standard deviation σ of the sampling distribution of X  are 25 and 4.74 respectively.

Step-by-step explanation:

Let X be the binomial random variable that represents the number of millenials in the sample who exercise daily.

As per given , the parameters associated with x are

n= 250 and p=0.10

Required formula ,

Mean = np

Standard deviation:

Similarly , the  mean μ and standard deviation σ of the sampling distribution of X will be :-

Mean =

Standard deviation:

Hence, the mean μ and standard deviation σ of the sampling distribution of X  are 25 and 4.74 respectively.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
