Suppose we are testing the null hypothesis HI]: pt = 1? against the alternative Ha: p :> 1? from a normal population with known standard deviation 0:4. A sample of size 289 is taken. We use the usual 2 statistic as our test statistic. Using the sample, a 2 value of 2.414 is calculated. (Remember: has a standard normal distribution.) a} What is the p value for this test? \\:| b] Would the null value have been rejected if this was a 1% level test'EI ON Ov c} Would the null value have been rejected if this was a 0.5% level test? ON Ov d] What was the value of E calculated from our sample? |:| e} Copyr your R script for the above into the text box here
