Is the length of time of unemployment related to the type of industry? A random sample of unemployed workers from three different work sectors yielded the following data. Perform a hypothesis test at 0.10 level of significance to determine if there is a relationship.

Question
Is the length of time of unemployment related to the type of industry? A random sample of unemployed workers from three different work sectors yielded the following data. Perform a hypothesis test at 0.10 level of significance to determine if there is a relationship.
Less than 5 weeks | 5-14 weeks | 15-26 weeks | |
Transportation | 89 | 115 | 77 |
Information | 64 | 65 | 43 |
Financial | 80 | 113 | 114 |
What are the expected numbers? (round to 3 decimal places)
Less than 5 weeks | 5-14 weeks | 15-26 weeks | |

The hypotheses are
H0:H0: The length of unemployment is independent of the type of industry.
HA:HA: The length of unemployment is dependent of the type of industry. (claim)
Since αα = 0.10 the critical value is 7.779
The test value is: (round to 3 decimal places)
The p-value is (round to 3 decimal places)
So the decision is to
- reject H0H0
- do not reject H0H0
Thus the final conclusion is
- There is not enough evidence to support the claim that the length of unemployment is dependent of the type of industry.
- There is enough evidence to support the claim that the length of unemployment is dependent of the type of industry.
- There is not enough evidence to reject the claim that the length of unemployment is dependent of the type of industry.
- There is enough evidence to reject the claim that the length of unemployment is dependent of the type of industry.
