Question
A pizza delivery driver recently complained that the college students he delivers to don't tip as much other
adults. Test this complaint at the a = 0.10 tevel of significance, Let uc represent the average tip left by
a college student and uo represent the average tip left by other adults.
Which would be correct hypotheses for this test?
O Ho: Hc = o, H:Hc > 0
Ho: HC
= Ho, H1: 4c + H0
Ho:c < Ho, H1: Hc = H0
Ho: Hc = Ho, H1:#c < Ho
A random sample of 30 college students had left an average tip of $3.31, with a standard deviation of
$1.17. A random sample of 48 non-college-student adults had left an average tip of $4.29, with a standard
deviation of $1.12.
Find the test statistic (2 decimal places):
Give the P-value (4 decimal places - if less than 0.001 answer 0):
Which is the correct result:
Reject the Null Hypothesis
Do not Reject the Null Hypothesis
Which would be the appropriate conclusion?
There is significant evidence to suggest that college students tip less, on average, than their non-
college-student adult counterparts.
There is not significant evidence to suggest that college students tip less, on average, than their
non-college-student adult counterparts.
