... A previous study reported that U. S. residents aged 18 to 24 years spend an average of 35.5 hours per month using the Internet. A new survey of 50
randomly selected participants obtained an average of 40.1 hours with a
standard deviation of 28.4 hours. Based on this survey, it is claimed that
this population now spends more time on the Internet, that is, more than
35.5 hours per month. Test this claim using the P-value method with a
0.01 significance level.
