Solve the Problem $\bar { x } = 56 , s = 16$

question 122

Multiple Choice

Solve the problem.
-How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 68 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: $\bar { x } = 56 , s = 16$ . Using the sample information provided, set up the calculation for the test statistic for the relevant hypothesis test, but do not simplify.

• A) \(z = \frac { 56 - 68 } { \frac { 16 } { \sqrt { 10,000 } } }\)
• B) \(z = \frac { 56 - 68 } { \frac { 16 } { 10,000 ^ { 2 } } }\)
• C) \(z = \frac { 56 - 68 } { 16 }\)
• D) \(z = \frac { 56 - 68 } { \frac { 16 ^ { 2 } } { 10,000 } }\)
