How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues
Used during a cold: $\overline{X}$ = 52, s = 22. Give the null and alternative hypotheses to determine if the number of tissues used during a cold is less than 60.

Question

How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues
Used during a cold:

\overline{X}

= 52, s = 22. Give the null and alternative hypotheses to determine if the number of tissues used during a cold is less than 60.

Quizplus · Accepted Answer

The null hypothesis should state that the population mean number of tissues used during a cold is equal to 60 (H0: µ = 60). The alternative hypothesis should state that the population mean number of tissues used during a cold is less than 60 (H1: µ < 60). 
Option D correctly states these hypotheses, while the other options either have incorrect symbols or incorrect statements.
