A sample of 25 students is obtained from a normal
population
with a standard deviation of 5. The students in the sample
have
a total score of 250 in a quiz. Then, the sampling
distribution
of the sample mean ̄x is N(10, 1).
true or false?
Homework Answers
We have been provided with the following information:
Now for the sample means we have:
Hence the distribution of

A sample of n = 16 scores is obtained from a population with a mean of 70 and standard deviation of 20. If the sample mean is 75, then the z-score corresponding to the sample mean is ____. Hint: You need to use the sampling distribution of the mean for a sample size of 16 and population standard deviation of 20.
