Question

Transcribed Image Text:A certain brand of tissues has 60 tissues in a standard box because the manufacturers believe that this is the average number of times people blow their nose during a cold. A research of the company checking on the validity of this claim, asked a random sample of 100 people to count the number of times they blow their nose during a cold. The mean of the sample was 57 and the standard deviation was 16. Do these data support the company’s belief? Should the company continue to put 60 tissues in a box? Use a two-tailed hypothesis testing procedure with α of 0.05. **Carry out all nine steps of the hypothesis testing procedure.**
