A random sample of
n
= 25 is obtained from a population with variance s2, and the sample mean is computed to be
x
= 70. Consider the null hypothesis


H0 : m = 80 versus the alternative hypothesis



H1 : m 6 80. Compute the
p-value for the following options.


a. The population variance is s2 = 225.


b. The population variance is s2 = 900.


c. The population variance is s2 = 400.


d. The population variance is s2 = 600.
