Suppose we are testing the null hypothesis HO: = 16 against the alternative Ha: < 16 from a normal population with known standard deviation g=4. A sample of size 289 is taken. We use the usual z statistic as our test statistic. Using the sample, aa value of -2.00 is calculated. (Remember z has a standard normal distribution.) } What is the p value for this test?L What was the value of x calculated from our sample?
