μx= ?????

Homework Answers

Answer #1

Solution :

Given that ,

mean = = 78

standard deviation = = 22

n = 264

sampling distribution of sample mean = 78

sampling distribution of standard deviation = / n = 22 / 264 = 1.3540

The population has mean μ=29 and standard deviation σ=9. This distribution is shown with the black dotted line. We are asked for the mean and standard deviation of the sampling distribution for a sample of size 34. The Central Limit Theorem states that the sample mean of a sample of size n is normally distributed with mean μx¯=μ and σx¯=σn√. In our case, we have μ=29, σ=9, and n=34. So, μx¯=29 and σx¯=934‾‾‾√=1.5 This distribution is shown with the red...
