Is the mean body temperature of humans different from 98.6degrees°​F?After randomly sampling 105 adults and determining their body​ temperature, a researcher found a​ 95% confidence interval for the mean body temperature of adult humans as (98.0degrees°​F, 98.4degrees°​F).What conclusion can be made based on this confidence​ interval? Choose the correct answer below. A.There is no evidence at a​ 5% significance level to say that the mean body temperature of adult humans is different from 98.6degrees°F. B.There is evidence at a​ 5%...
