Question

How many tissues should the Kimberly Clark Corporation package of Kleenex contain?Researchers determined that 60 tissues is the mean 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:

\bar { X } = 52

, S = 22.Suppose the test statistic does fall in the rejection region at

\alpha

= 0.05.Which of the following decision is correct?

A)$\text { At } \alpha = 0.05 \text {, you do not reject } H _ { 0 }$ 
B)$\text { At } \alpha = 0.05 \text {, you reject } H _ { 0 } \text {. }$ 
C)$\text { At } \alpha = 0.05 , \text { you do not reject } H _ { 0 }$ 
D)$\text { At } \alpha = 0.10 , \text { you do not reject } H _ { 0 }$

Quizplus · Accepted Answer

Given that the test statistic falls in the rejection region at $\alpha = 0.05$, the correct decision is to reject the null hypothesis $H_0$.
