In conducting the hypothesis test below, your sample consists of 28 observations, with a mean of 5.4 and standard deviation of 3.22. Hg:p:3.5 H1:p% 3.5 a) This is a b) Calculate the test statistic, rounded to 3 decimal places. t=| | c) At a: : 0.1, the rejection region is Oi; 1.703 {It > 1.314 (I) none of the above cl) The decision is to C- reject H0 since the test statistic falls in the rejection region. C- fail to reject Hg since the test statistic does not fall in the rejection region. (3- fail to reject H1 since the test statistic does not fall in the rejection region. (3- reject H1 since the test statistic falls in the rejection region. C:- none of the above
