Do consumers spend more on a trip to Target or Walmart? Suppose researchers interestedin this question collected a systematic sample from 81 Target customers and 77 Walmartcustomers by asking customers for their purchase amount as they left the stores. The datacollected is summarized by the accompanying table. Suppose researchers decide to testthe hypothesis that the means are equal. The degrees of freedom formula gives 155.63 df.Test the null hypothesis at x = 0.01.OA. Ho: HA-HB = 0HA: HA-HB >0B. Ho: HA-HB = 0HA: HA-HB #0OC. Ho: HA-HB=0HA: HA-HB <0D.

A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 54 men and 70 women to participate in the study. Each subject was required to step up and down a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained.

In the fictional city of Statisticsville, last year residents spent an average of $12 per month using grocery pickup services (where you purchase groceries online and then drive to the store to pick them up). A journalist wants to know if people today in the (fictional) city of Statisticsville are spending more per month on average compared to last year. Her hypotheses are: Hoi u =12 HA: H> 12 She selects a random sample of 89 people at a large public space in Statisticsville and finds their average spending per month on grocery pickup fees is $12.19 with a standard deviation of $4.15. All necessary assumptions and conditions have already been checked and were met. 1) What are the degrees of freedom (DF) for the t-distribution for performing this hypothesis test? 88 (Enter an integer answer.) 2) What is the value of the t-statistic for performing this hypothesis test? (Round your answer to 2 decimal places.) 3) Which of the following statements about the value is most appropriate? (You…
As part of an investigation into motorway accidents in Greater Manchester, it was hypothesised that weather conditions were an important factor. Research revealed that in wet weather the M61, M62 and M63 experienced 32, 272 and 96 accidents. In dry weather, the figures were 32, 281 and 30. i. Formulate null and alternative hypothesis for this test ii. Calculate the chi-squared statistic iii. State the degrees of freedom in this case. iv. Test the chi-square statistic at 1% level and state your conclusions in everyday language.
