Confidence Interval: Suppose x has a mound-shaped distribution with  = 6. A random sample of
size 16 has sample mean 50.
(a) Check Requirements: Is it appropriate to use a normal distribution to compute a confidence
interval for the population mean µ? Explain.
(b) Find a 90% confidence interval form.
(c) Interpretation: Explain the meaning of the confidence interval you computed.

A random variable is not normally distributed, but it is mound shaped. It has a mean of 17 and a standard deviation of 5. If you take a sample of size 13, can you say what the shape of the sampling distribution for the sample mean is? Why? If the sample size is 13, then you can't say anything about the sampling distribution of the sample mean, since the population of the random variable is not normally distributed and the...
