When individuals in a sample of 150 were asked whether or notthey supported capital punishment, the following information was obtained. Do you support Number of capital punishment? individuals Yes 40 No 60 No Opinion 50We are interested in determining whether or not the opinionsof the individuals (as to Yes, No and No Opinion) are uniformlydistributed.The expected frequency for each group is?a.) 0.333b.) 0.50c.) 1/3d.) 50The calculated value for the test statistic equals?a.) 2b.) -2c.) 20The number of degrees of freedom associated with this problemis ?a. 150b. 149c. 2d. 3The p-value is ?a. larger than0.1b. less than 0.1c. less than 0.05d. larger than 0.9The conclusion of the test(at 95% confidence) is thatthea. distribution is uniformb. distribution is not uniformc. test is inconclusived.

Answer 1

Answer:

a. distribution is uniform

Step-by-step explanation:

Given that  a sample of 150 were asked whether or notthey supported capital punishment.

3)

we prepare contingency tab

Expected = 50 50 50

Chisquare = 4

chi square 2 2 0 4

p value 0.135

Since p >0.05 we accept H0

a. distribution is uniform
