In a specific year 53.7% of men (sample 1) in the United States were married and 50.3% of women (sample 2) were married. Random samples of 300 men and 300 women found that 174 men and 138 women were married (not necessarily to each other). At the 0.01 level of significance, can it be concluded that the proportion of men who were married is greater than the proportion of women who were married? a) State the hypotheses and identify the claim with the correct hypothesis. 01. Ho:P1 = P2 Not claim H1:21 >p2 claim O2. Ho:P1 =P2 Not claim H:P1 P2 claim 3. Ho:P1 P2 Not claim H1:21 2 claim
b) Find the critical value (s). 01. CV=1.65 O 2. CV=2.33 O3. CV= -2.58 c) Compute the test value: 01. z=2.38 O 2. z=2.94 03. Z= 2.52 d) Make the decision. 01. Reject the null hypothesis. 2.Do not reject the null hypothesis. e) Summarize the results. 01. There is enough evidence to support the claim. 2.There is not enough evidence to support the claim.
