In conducting the hypothesis test below, your sample consists of 27 observations, with a mean of 40.5 and standard deviation of 1.82.

H0:=40.8

H1:40.8

a) This is a..................

b) Calculate the test statistic, rounded to 3 decimal places.

t=

c) At=0.1

the rejection region is

• t<-1.706 ort >1.706
• t<-1.315
• t>1.315
• none of the above

d) The decision is to

• rejectH1 since the test statistic falls in the rejection region.
• rejectH0 since the test statistic falls in the rejection region.
• fail to rejectH1 since the test statistic does not fall in the rejection region.
• fail to rejectH0since the test statistic does not fall in the rejection region.
• none of the above
