Multiple Choice
The article from a local newspaper states that there was convincing evidence of a dependence between the preferred cultural outings (cinema, concerts, exhibitions, or theater) and the presence of children. The author makes a conclusion that having children can affect people's leisure, they may start to prefer cultural outings different from those that they had attended before. Citizens who have kids are more likely to go to theaters and exhibitions. Use the Minitab output and a 0.05 significance level to carry out a chi-squared test for independence. Is it justified to conclude that cultural outings are more preferable for families with children?
A) The conclusion is correct, because the P-value is rather small.
B) The conclusion is incorrect, because the discrepancies between the observed and expected counts are not large enough.
C) The conclusion is correct, because the sample sizes are large enough to justify the results.
D) The conclusion is incorrect, because the value of the statistic is not significant.
E) The conclusion is incorrect, because the test results do not imply a causal relationship.
