Solve the Problem $\bar { x } = 47 , s = 20$

question 52

Multiple Choice

Solve the problem.
-How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 61 tissues during a cold. Suppose a random sample of 10,000 people yielded the following data on the number of tissues used during a cold: $\bar { x } = 47 , s = 20$ . We want to test the alternative hypothesis $H _ { \mathrm { a } } : \mu < 61$ . State the correct rejection region for $\alpha = .05$ .

• A) Reject \(H _ { 0 }\) if \(z > 1.645\).
• B) Reject \(H _ { 0 }\) if \(z < - 1.96\).
• C) Reject \(H _ { 0 }\) if \(z < - 1.645\).
• D) Reject \(H _ { 0 }\) if \(z > 1.96\) or \(z < - 1.96\).
