Skill: Determine the sampling distribution of the sample proportion and the sample mean in a given situation and apply it to determine likelihoods.

"multiple choice" question: select the correct answer. 

What is the mean and standard deviation of the sampling distribution of x¯, the average number of defects in a sample of size n=225?

Resposta Selecionada: Mean = 3.6, standard deviation = 0.5

Resposta Correta: Mean = 3.6, standard deviation = 0.5

Feedback da resposta:This is correct. The mean and standard deviations are μ=3.6 and σn√=7.5225√=0.5, repectively.
