Question

Name: ID: c ution goodness of fit chi-square) test, there are 3 (k -3) categories and the expected more for all categories. The following results are found: Calculated chi-square (z?) value 16.832 Critical chi-square ) value-10.597 Based on these information, what is the conclusion? A Accept Ho: The population follows a multinomial distribution with specified probabilities for each of the 3 categories and reject Hi: not Ho Reject H : The population follows a multinomial distribution with specified probabilities for each of the 3 categories and accept Hi: not Ho Accept Ho: The population does not follow a multinomial distribution with specified probabilities for each of the 3 categories and reject H: not Ho Not enough information given to answer this question None of the above E 11. In a t test for significance in multiple linear regression, the significance level (a) is equal to 0.10, the sample size (m) is equal to 12 and the number of independent variables (p) is equal to 2. Based on these information, what are the critical t values?

The significance level () is equal to 0.025. Based on these information, what is the critical chi-square ) value? 13. D 7.37 C 9.210 Not enough information given to answer this question None ofthe above

Explanation / Answer

10) as test stat is higher than critical value

option b is correct

11)

for degree of freeedom =n-p =12-3=7

hence critical vlaue at 9 df and 0.1 level =-/+ 1.833

option B is correct

12)for 14 df and 0.2 level

option A is correct

13)

critical chi square value for (3-1=2) df and 0.025 level =7.378

option B is correct
