C) Do not reject $H_0$ at $\alpha = 0.10$ and do not reject $H_0$ at $\alpha = 0.05$

D) Reject $H_0$ at $\alpha = 0.10$ and do not reject $H_0$ at $\alpha = 0.05$

Individuals filing federal income tax returns prior to March 31 received an average refund of $1056. Consider the population of "last-minute" filers who mail their tax return during the last five days of the income tax period.

b. For a sample of 400 individuals who filed a tax return between April 10 and 15 , the sample mean refund was$\$910$. Based on prior experience, a population standard deviation of $\sigma=\$ 1600$ may be assumed. What is the $p$-value?
