Question 537195: Hi,
Claim: The population mean is 425. Sample data: n = 18, x bar = 438, s = 21.3. The data was taken from a simple random sample collected from a normally distributed population with a population standard deviation of 18.4.
I need to state the null and alternative hypothesis (I currently have Ho: p = 425 and H1: p > 425) and then state the sampling distribution of the test statistic (normal, t, or chi-square). I have a normal distribution. Am I correct?
Any help would be great!

I need to state the null and alternative hypothesis.
-------
Ho: u = 425
H1: u is not equal to 425
-------
State the sampling distribution of the test statistic (normal, t, or chi-square).
