In conducting the hypothesis test below, your sample consists of 16 observations, with a mean of 43.6 and standard deviation of 2.21. H0:=42.8 H1:42.8 a) This is a Select an answer right-tailed test. left-tailed test. no-way test. two-tailed test. none of the above b) Calculate the test statistic, rounded to 3 decimal places. t= c) At =0.05, the rejection region is

• t>1.753
• t<-2.131 or t>2.131
• t<-1.753
• none of the above

d) The decision is to

• reject H0 since the test statistic falls in the rejection region.
• fail to reject H1 since the test statistic does not fall in the rejection region.
• reject H1 since the test statistic falls in the rejection region.
• fail to reject H0 since the test statistic does not fall in the rejection region.
• none of the above
