Question

Suppose you are conducting a test of independence. Specify the critical value under the following scenarios (Use Table 3): |

a. |
r = 4, c = 5, and ? =
0.10. (Round your answer to 3 decimal
places.) |

Critical value |

b. |
r = 4, c = 6, and ? =
0.05. (Round your answer to 3 decimal
places.) |

Critical value |

Answer #1

**Solution

Suppose you are conducting a test of independence for two
categorical variables in a contingency table
(cross-tabulation) consisting of three rows. If the critical value
at the 1% level of significance is 23.209.
How many columns were in the contingency table?

Conduct the hypothesis test and provide the test statistic and
the critical value, and state the conclusion.
A person drilled a hole in a die and filled it with a lead
weight, then proceeded to roll it 200 times. Here are the observed
frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively:
28, 27, 40, 38, 26, 41. Use a 0.01 significance level to test the
claim that the outcomes are not equally likely. Does it...
