How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 40 tissues during a cold. Suppose a random sample of 2500 people yielded the following data on the number of tissues used during a cold: $\bar { x } = 34 , s = 20$. Suppose the corresponding test statistic falls in the rejection region at $\alpha = .05$. What is the correct conclusion?
A) At $\alpha = .10$, reject $H _ { \mathrm { a } }$.
B) At $\alpha = .10$, reject $H _ { 0 }$.
C) At $\alpha = .05$, reject $H _ { 0 }$.
D) At $\alpha = .05$, accept $H _ { \mathrm { a } }$.
