# Question

Consider the following hypotheses:

H0: µ = 1800

HA: µ ≠ 1800

The population is normally distributed with a population standard deviation of 440. Compute the value of the test statistic and the resulting p-value for each of the following sample results. For each sample, determine if you can reject the null hypothesis at the 10% significance level.

a. = 1850; n = 110

b. = 1850; n = 280

c. = 1650; n = 32

d. = 1700; n = 32
