I need help with letter C and D
![Question No. 5
Recall that "very satisfied" customers give the XYZ-Box video game system a rating that is at least 42.
Suppose that the manufacturer of the XYZ-Box wishes to use the random sample of 65 satisfaction ratings
to provide evidence supporting the claim that the mean composite satisfaction rating for the XYZ-Box
exceeds 42.
A. Letting m represent the mean composite satisfaction rating for the XYZ-Box, set up the null
hypothesis H0 and the alternative hypothesis Ha needed if we wish to attempt to provide
evidence supporting the claim that u exceeds 42.
B. The random sample of 65 satisfaction ratings yields a sample mean of 42.954. Assuming that
the population standard deviation equals 2.64, use critical values to test HO versus Ha at each
of a = 10, .05, .01, and .001.
C. Using the information in part b, calculate the p-value and use it to test HO versus Ha at each of
a = 10, .05, .01, and .001
D. How much evidence is there that the mean composite satisfaction rating exceeds 42?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4814aa55-33a9-4793-9da4-13ade01b3b25%2F697a1822-799c-4d34-a29a-5d26201ed11f%2Fiho9uc_processed.jpeg&w=3840&q=75)
