Suppose we are testing the null hypothesis H0: μ = 13 against the alternative Ha: μ < 13 from a normal population with known standard deviation σ=4. A sample of size 289 is taken. We use the usual z statistic as our test statistic. Using the sample, a z value of -2.33 is calculated. (Remember z has a standard normal distribution.) c) Would the null value have been rejected if this was a 1% level test? Yes or No d) What was the value of x calculated from our sample?
