The Statistical Bulletin published by Metropolitan Life Insurance Co. reported that 2% of all American births result in twins. If a random sample of 8000 births is taken, find the mean, variance, and standard deviation of the number of births that would result in twins
Solutions
Expert Solution
Solution:
μ = 8000 * 0.02 = 160
σ ^2 = 8000 * 0.02 * 0.98 = 156.8
σ = Sqrt(156.8) = 12.5

A recent issue of AARP Bulletin reported that the average weekly
pay for a woman with a high school diploma was $520. Suppose you
would like to determine if the average weekly pay for all working
women is significantly greater than that for women with a high
school diploma. Data providing the weekly pay for a sample of 50
working women are available in the Excel file (Weekly Pay).
Formulate the null and alternative hypotheses...

"A survey published in the American Journal of Sports Medicine2
reported the number of meters (m) per week swam by two groups of
swimmers—those who competed for exclusively in breaststroke and
those who competed in the individual medley(which includes
breaststroke). The number of meters per week practicing the
breaststroke was recorded for each swimmer, and the summary
statistics are given below. Is there sufficient evidence to indicate
that the average number of meters per week spent practicing
breaststroke is greater...

a.
Determine the probability that the sampling error made in
estimating the population mean life insurance in force by that of a
sample of 500 covered families will be $2000 or less

Question 2: The American Journal of Clinical Nutrition
published the results of a study of the dietary intake of sugar by
children.
In the trial a sample of 657 randomly selected American
children between the ages of 5 and 12 was chosen, and for each
child a seven day food diary was filled in. An analysis of the data
showed a sample mean of 134.3 g of sugar per day with a standard
deviation of 48.1 g. Using the results...
