I just need B answered.....not sure how to get X2 or P-value
Do males and females have the same distribution of mode of transportation on a Saturday night? Suppose that 450 randomly selected people at a club are asked about how they plan to get home—drive, drive with a friend, take public transit, or take a cab. Use a level of significance of
? = 0.05.
| Drive | Public Transit | Cab | Total | |
|---|---|---|---|---|
| Male | 72 | 83 | 50 | 205 |
| Female | 91 | 66 | 88 | 245 |
| Total | 163 | 149 | 138 | 450 |
(a)
What are the expected values ? (Round your answers to three decimal places.)
| Drive | Public Transit | Cab | |
|---|---|---|---|
| Male | 74.256 | 67.877 | 62.866 |
| Female | 88.744 | 81.122 | 75.133 |
(b)
Calculate the
χ2
test statistic and P-value. (Use technology. Round your answer for the
χ2
test statistic to two decimal places and the P-value to four decimal places.)χ2
test statisticP-value(c)
What is the appropriate conclusion?
Reject
H0
because
P-value > 0.05.
Reject
H0
because
P-value < 0.05.
Fail to reject
H0
because
P-value > 0.05.
Fail to reject
H0
because
P-value < 0.05.
