Answer #1

Solution :

Given that,

mean = = 40

standard deviation = = 4

n = 16

The sampling distribution of mean and standard deviation is ,

= 40

= / n = 4 / 16 = 1

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...
