thanks for help

Suppose a population is Normally distributed with sigma, o = 3. A random sample of 36 observations is drawn from the population and we find the sample mean of these observations is x-bar, & = 12. We test the null hypothesis Ho: H = 10 and the alternative Ha: [ > 10. A. What is the value of the test statistic z? B. What is the P-value? Would you reject or fail to reject the null at the 1% significance level? Why? lit Format Table t Paragraph B I U AV & V T? V
