The average remaining lifetimes for women of various ages in a certain country are given in the following table.
Suppose that the incidence rate pf myocardial infraction (MI) was 5 per 100 among 45 - 50 year old men in 2000. To look at changes in incidence over time, 5000 men in this age groups were followed for 1 year starting in 2010. Twenty new cases of MI were found. Suppose we eventually plan to accumulate 50 MI cases during the period 2010-2015. Suppose that 20% of the patients with MI in 2000 died within 24 hours. This proportion is called the 24 hour case fatality rate. A test is performed to see if the true proportion of 24 hour case fatality rate differs from 20%, with significance level of 0.01. Assume that the 24-hour case fatality rate is truly 25% during the period. how large a sample is needed to achieve 92% power?
Suppose losses follow a uniform distribution from 0 to 30,000. If there is a deductible of 3000, and maximum covered loss of 25000, what is the average payment per loss? Repeat above question, but calculate average amount paid per non-zero payment.

Suppose that historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous 6 months, in a sample of 115 new-car buyers, 46 have traded in their old car. To determine whether the proportion of new car buyers that trade in their old car has statistically significantly decreased, what is the p-value? (please round your answer to 4 decimal places)

According to a 2006 survey conducted by the Center for Disease Control and Prevention (CDC), birth rates peak slightly between July and October each year. While a slight numerical increase in birth rates is often observed, this difference is assumed to be statistically non-significant. Thus, we would expect to see an equal number of people born during each month of the year in the United States. The "Birth Data.jasp" contains the birth months for 1380 babies (N = 1380) born during the year 2006 in the United States collected by the CDC. Conduct a Chi-Square Goodness of Fit Test at α = 0.05, to see if the number of babies born each month “fits” with the CDC’s assumptions about the population. Identify the correct alternative hypothesis A. H0: The number of babies born throughout the year is equal across all 12 months B. HA: The number of babies born in at least one month of the sample is equal to the number of babies born in at least one month of the population C. HA: The…
