Astudy was conducted to measure the effectiveness of hypnotism in reducing pain. the measurements are centimeters on a pain scale before and after hypnosis. assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal. construct a 95% confidence interval for the mean of the"before minusâafter"differences. does hypnotism appear to be effective in reducingpain?

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$â˘79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$â˘19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$â˘75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$â˘21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let Îź1Îź1 be the true mean repair cost for type i ovens and Îź2Îź2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
