Part 2 and 3 

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 level of significance. Let µc represent the
average tip left by a college student and
tip left by other adults.(Round your results to three decimal
places)
represent the average
Which would be correct hypotheses for this test?
OH = Ort:1H Orl > Orl:0H
Η: με- μο, Η : μα > μο
Ho : µc = Ho, H1 : µc < µo
| Ho : µc = Po, Hị:µc + µo
A random sample of 38 college students had left an average tip of
$5.29, with a standard deviation of $1.03. A random sample of 47
non-college-student adults had left an average tip of $6.45, with a
standard deviation of $0.86.
Find the test statistic (2 decimals):
Give the P-value (4 decimals):
Which is the correct result:
O Do not Reject the Null Hypothesis
Reject the Null Hypothesis
Which would be the appropriate conclusion?
O There is significant evidence to suggest that college students
tip less, on average, than their non-college-student adult
counterparts.
OThere is not significant evidence to suggest that college
students tip less, on average, than their non-college-student
adult counterparts.
