In conducting the hypothesis test below, your sample consists of 24 observations, with a mean of 43 and standard deviation of 4.16. H0:43.2H0:43.2 H1:<43.2H1:<43.2 a) This is a Select an answer >

left-tailed test. no-way test. right-tailed test. two-tailed test. none of the above b) Calculate the test statistic, rounded to 3 decimal places. t= c) At =0.1=0.1, the rejection region is

• t<-1.319t<-1.319
• t>1.319t>1.319
• t<-1.714ort>1.714t<-1.714ort>1.714
• none of the above

d) The decision is to

• fail to reject H0H0 since the test statistic does not fall in the rejection region.
• reject H0H0 since the test statistic falls in the rejection region.
• reject H1H1 since the test statistic falls in the rejection region.
• fail to reject H1H1 since the test statistic does not fall in the rejection region.
• none of the above
