1. The conclusion of the test (alpha = 0.05) is that the:

A) distribution is uniform

B) distribution is not uniform

C) test is inconclusive

D) none of these alternatives is correct

2. The hypothesis is to be tested at the 5% level of significance. The critical value from the table equals:

When individuals in a sample of 150 were asked whether or not they supported capital punishment, the following information was obtained. We are interested in determining (alpha=.05) whether or not the opinions of the individuals (as to Yes, No, and No Opinion) are uniformly distributed. 1. The conclusion of the test (alpha = 0.05) is that the: A) distribution is uniform B) distribution is not uniform C) test is inconclusive D) none of these alternatives is correct 2. The hypothesis is to be tested at the 5% level of significance. The critical value from the table equals: A) 5.99147 B) 9.34840 C) 7.37776 D) 7.81473

Solution

(1) The test hypothesis:

Ho:distribution is uniform (i.e. null hypothesis)

Ha:distribution is not uniform (i.e. alternative hypothesis)

observed

expected

O - E

(O - E)
