Round to 3 decimal points and are the questions I answered correct?

Suppose we are testing the null hypothesis HO: / = 16 against the alternative Ha: / > 16 from a normal population with known standard deviation o=4. A sample of size 324 is taken. We use the usual z statistic as our test statistic. Using the sample, a z value of 2.14 is calculated. (Remember z has a standard normal distribution.) a) What is the p value for this test? |0.016 b) Would the null value have been rejected if this was a 2% level test? ON OY c) Would the null value have been rejected if this was a 1% level test? OY ON d) What was the value of x calculated from our sample? e) Copy your R script for the above into the text box here
