16-20 71 70
21-25 82 58
More than 25 118 79

(a) Is it reasonable to conclude that there is an association between gender and the number of vacation days taken?

Test the appropriate hypotheses using a 0.05 significance level. Calculate the test statistic. (Round your answer to two decimal places.)
χ2 =

P-value interval

p < 0.0010.001 ≤ p < 0.01    0.01 ≤ p < 0.050.05 ≤ p < 0.10p ≥ 0.10


There is  ---Select--- enough evidence not enough evidence to conclude that there is an association between gender and the number of vacation days taken.
