Conduct a hypothesis test to determine if there has been more than a 0.04 increase in the proportion of students who indicated they have been diagnosed with depression.Use a significance level of 0.05 and a p-value approach to this test.

• A)Since p-value = 0.065 > 0.05,do not reject H_0.There is not sufficient evidence to conclude that there has been more than a 0.04 increase in the proportion of students that indicate they have been diagnosed with depression.
• B)Since p-value = 0.025 < 0.05,reject H_0.There is sufficient evidence to conclude that there has been more than a 0.04 increase in the proportion of students that indicate they have been diagnosed with depression.
• C)Since p-value = 0.072 < 0.05,reject H_0.There is sufficient evidence to conclude that there has been more than a 0.04 increase in the proportion of students that indicate they have been diagnosed with depression.
• D)Since p-value = 0.071 > 0.05,do not reject H_0.There is not sufficient evidence to conclude that there has been more than a 0.04 increase in the proportion of students that indicate they have been diagnosed with depression.
