Question

Before the furniture store began its ad campaign, it averaged 137 customers per day. The manager is investigating if the average is larger since the ad came out. The data for the 14 randomly selected days since the ad campaign began is shown below: 

169, 142, 165, 129, 120, 124, 121, 126, 136, 168, 128, 145, 154, 125

Assuming that the distribution is normal, what can be concluded at the αα = 0.05 level of significance?

  1. For this study, we should use Select an answer z-test for a population proportion t-test for a population mean 
  2. The null and alternative hypotheses would be:     

 H0:H0:  ? μ p  Select an answer ≠ > < =       

 H1:H1:  ? μ p  Select an answer > ≠ < =    

  1. The test statistic ? z t  =  (please show your answer to 3 decimal places.)
  2. The p-value =  (Please show your answer to 4 decimal places.)
  3. The p-value is ? > ≤  αα
  4. Based on this, we should Select an answer reject accept fail to reject  the null hypothesis.
  5. Thus, the final conclusion is that ...
    • The data suggest that the pop

    Ans 3 4 and 5 only
