question 129

Multiple Choice

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 2500 people yielded the following data on the number of tissues used during a cold: $\bar { x } = 51 , s = 25$ . 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 \(\alpha = .05\), accept \(H _ { \mathrm { a } }\).
• D) At \(\alpha = .05\), reject \(H _ { 0 }\).
