Bad Dawgz is hosting its annual hot dog eating competition which involves eating 14 hot dogs, six inches in length. The following attached data represent the times (in seconds) taken by each contestant to eat the first hot dog and the fourteenth (last) hot dog. Twelve contestants finished all 14 hot dogs. a. Calculate a 90% confidence interval for the mean time taken by each contestant to eat the (i) first hot dog and (ii) last hot dog. b. Test the hypothesis that the difference between the two mean times for both is 35 seconds. Use the 5% level of significance. c. Subsequently, it was learnt that the times for the last hot dog were incorrectly recorded and that each of the values is 10 seconds too large. What, if any, difference does this make to the results of the test done in part (b)? Show all steps for the hypothesis test.
