It has been found in previous studies that 71% of all teenage marriages end in divorce. In order to test this statistic, a sample of 87 couples married as teenagers were followed for twenty-five years to determine if they stayed married or not. Out of the 87 couples surveyed, 68 ended in divorce. At the .05 los, can we conclude that more than 71% of teenage marriages end in divorce? 3 pts for (a) – (e)

a) State the null and alternate hypothesis:

b) Name the Test: ________________________

c) Show that the conditions needed to perform this test are satisfied:

d) Determine the P-value: ___________________________ (round to 4 places .

e) Determine whether to Reject H0 or Fail to Reject H0 , and TELL WHY by relating P-value to α:

It has been found in previous studies that 70% of all teenage smokers end up quitting. In order to test this statistic, a sample of 87 teenage smoker were followed for twenty-five years to determine if they continued smoking or not. Out of the 87 teenagers surveyed, 68 ended up quitting. At the .05 los, can we conclude that more than 70% of teenage smokers ended up quitting? a) State the null and alternate hypothesis: b) Name the Test: ________________________...

The overall divorce rate (i.e., the number of divorces divided by the number of marriages) has fallen dramatically since the 1980s. Since the rate is calculated relative to the number of marriages, this cannot be chalked up to fewer marriages. People who get married today have a much higher likelihood of staying married relative to thirty years ago. How might you use our economic principles to explain this result? Explain.

From previous studies, it has been generally believed that Northern Hemisphere icebergs have a mean depth of 270 meters. An environmentalist has suggested that global warming has caused icebergs to have greater depth. A team of scientists visiting the Northern Hemisphere observed a random sample of 41 icebergs. The depth of the base of the iceberg below the surface was carefully measured for each. The sample mean and standard deviation were calculated to be 276 meters and 20 meters respectively....

Adequate Preparation for Retirement. In 2018, RAND Corporation researchers found that 71% of all individuals ages 66 to 69 are adequately prepared financially for retirement. Many financial planners have expressed concern that a smaller percentage of those in this age group who did not complete high school are adequately prepared financially for retirement. a. Develop appropriate hypotheses such that rejection of H0 will support the con-clusion that the proportion of those who are adequately prepared financially for retirement is smaller...
