A research tea believes that the weight of Grizzly adule male bears are normally distributed. A simple random saple of 23 Grizzly male bears yielded a mean weight of 277kg and a variance of 121. Let μ denote the mean weight for Grizzly adult male bears. Suppose the research teams wants to test, at the 5 % level of significance, whether the mean weight for Grizzly adult male bears is greater than 271kg. Suppose the assumptions to this hypothesis test are satisifed. d) what is the observed test statistic for hypothesis test? e) What is the correct conclusion for this hypothesis test? Since the observed test statistic is greater than the critical value we reject do not H0, at the 5% level of significance Since the observed test statistic is greater than the critical value we reject H0 at the 5% level of significance Since the observed test statistic is less than the critical value we do not reject H0 at the 5% level of significance Since the observed test statistic is less than the critical value we reject H0 at 5% level of significance f)What is the 98% confidence interval for μ?
