Hi everyone,
I'm studying for my statistics exam and I came across this question which I don't quite understand and was hoping someone could give me some help.


The questions is: Report the P value for this example:


When the 127 workers aged 18-25 in the 2008
GSS were asked how many hours they worked in
the previous week, the mean was 37.47 with a SD
of 13.63. Does this suggest the population mean
work week for this age group differs from 40 hours
(at the 5% level of significance)?


The answer says that the p- value is .04 but I don't understand how that is correct


thanks in advance :)
