You wish to test the following claim (Ha) at a significance level of=0.005.
Ho:=72.7
Ha:<72.7
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of sizen=107with meanM=71.7 and a standard deviation ofSD=12.6.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
