Customers at a large grocery chain spend no more than $130 per trip. After a city-wide ad campaign, the marketing department would like to determine if the customers are spending more than $130 per trip. The next 25 customers averaged $135.25 per trip with the sample standard deviation of $10. At 0.05 signifiance level, test if the customers are spending more than $130. 1. Which of the following (A,B,C,or D) would be the correct hypothesis statement? A. Ho: p s 0.25 Hạip > 0.25 В. Но: д > 130 Н: д < 130 C. Ho: μ <= 130 Ha μ > 130 D. Ho: μ 36 H μ36 2. The critical value is 3. The statistical value in this problem is ... 4. The p-value range associated with the test statistic is ... 5. At a 5% level of significance, will the decision be to Reject or DNR?
