A recent national report states the marital status distribution of the male population age 18 or older is as follows: Never Married (31.1%), Married (56.1%), Widowed (2.6 %), Divorced (10.2 % ) . The table below shows the results of a random sample of 1980 adult men from California. Test the claim that the distribution from California is as expected at the ax = 0.01 significance level. a. Complete the table by filling in the expected frequencies. Round to the nearest whole number: Frequencies of Marital Status Outcome Frequency Expected Frequency Never Married 602 Married 1110 Widowed 54 Divorced 214 b. What is the correct statistical test to use? Select an answer c. What are the null and alternative hypotheses? Ho: Marital status and residency are independent. The distribution of marital status in California is the same as it is nationally. Marital status and residency are dependent. The distribution of marital status in California is not the same as it is nationally. H₁: The distribution of marital status in California is not the same as it is nationally. The distribution of marital status in California is the same as it is nationally. Marital status and residency are dependent. O Marital status and residency are independent. d. The degrees of freedom = e. The test-statistic for this data = f. The p-value for this sample= (Please show your answer to three decimal places.) (Please show your answer to four decimal places.)
