Transcribed Image Text:Suppose you must test the hypothesis at 5% level of
significance whether the mean time taken to find their
first full-time job for all May 2019 graduates in these
fields is the same. What is your conclusion?
a) Since F=2.092 is greater than"a
F=4.21
we then fail reject the null hypothesis at 5% level of significance and conclude that all the means
are equal.
F -4.21
b) Since F=2.092 is not greater than
we then fail reject the null hypothesis at 5% level of significance and conclude that all the
means are not equal.
F =4.21
c) Since F=2.092 is not greater than
.we then reject the null hypothesis at 5% level of significance and conclude that all the means
are equal.
F =4.21
d) Since F=2.092 is not greater thana
, we then fail reject the null hypothesis at 5% level of significance and conclude that all the
means are equal.

Transcribed Image Text:A university employment office wants to compare the
time taken by graduates with three different majors to
find their first full-time job after graduation. The
following table lists the time (in days) taken to find their
first full-time job after graduation for a random sample
of eight business majors, seven computer science
majors, and six engineering majors who graduated in
May 2019.
