Let x stand for the number of calories in each individual snack. 25 snacks are sampled at a time. The population mean is 95 calories and the population standard deviation is 2.5 calories. What is the mean and standard deviation of the sampling distribution of sample means? a. mean = 19. standard deviation = 2.5
b. mean = 95, standard deviation = 0.5
c. mean = 95, standard deviation = 2.5
d. mean = 19. standard deviation = 0.5

b)

Mean of the sample μₓ = 95

Standard deviation of the sample (S) = 0.5

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 25

Mean of the Population μ = 95 calories

Standard deviation of the Population = 2.5 calories

Step(ii):-

Mean of the sample μₓ = μ

Mean of the sample μₓ = 95

Standard deviation of the sample

if u need it to be negative.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
