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 0.01
level of significance to determine if there is a relationship.

5-14 weeks
15-26 weeks

What are the expected numbers? (round to 3 decimal places)
Less than 5 weeks
5-14 weeks
15-26 weeks
Transportation
Information
Financial
The hypotheses are
Ho: The length
unemployment is independent
the type of industry.
HA: The length of unemployment is dependent of the type of industry. (claim)
Since a = 0.01 the critical value is 13.277
The test value is:
(round to 3 decimal places)
The p-value is
(round to 3 decimal places)
So the decision is to
O reject Ho
O do not reject Ho
Thus the final conclusion is
O There is enough evidence to support the claim that the length of unemployment is dependent of the
type of industry.
O There is not enough evidence to support the claim that the length of unemployment is dependent of
the type of industry.
O There is not enough evidence to reject the claim that the length of unemployment is dependent of
the type of industry.
O There is enough evidence to reject the claim that the length of unemployment is dependent of the
type of industry.

Transportation 89 114 81 284
Information 58 70 55 183
Financial 81 113 112 306

Expected value of a cell = Row sub total * Column sub totalGrand total

 

Example ( E(Transportation , less than 5 weeks) = 284*22877383.767

 

Similarly for others

 

df = (# rows -1 ) (# column - 1) 

    = (3-1)(3-1) = 4
