Skitzy Schizophrenic at the American Medical Association wrote a report recently that stated the average annual salary of psychiatrists is $185,000  with a population standard deviation of $27,000 (σ= 27000).  A group of hospital administrators in the Northeast randomly sampled 64 psychiatrists (n = 64) to test to see if psychiatrists in their region have a different average.  Their sample was found to have an average annual salary of $194,630 .   

  1. Conduct a hypothesis test to determine if the average salary at this Northeast hospital is significantly different from the national average reported by Skitzy. Test using the traditional method using α = 0.01.
  1. What is the p-value for the hypothesis test found in part 2a?

According to a 1996 report on full-term pregnancies by the American Medical Association, women pregnant with twins who received intensive prenatal care had an infant mortality rate of 5.4 deaths per thousand live births, while women pregnant with twins who received only adequate care had an infant mortality rate of 3.9 deaths per thousand live births. Does this suggest that a woman pregnant with twins should be concerned about seeking too much medical care? Explain fully in one or two...

Six months before its annual convention, the American Medical Association must determine how many rooms to reserve. At this time, the AMA can reserve rooms at a cost of $50 per room. All rooms that are reserved must be paid for even if they are not used. The AMA believes the number of doctors attending the convention will be normally distributed with a mean of 5000 and a standard deviation of 1000. If the number of people attending the convention...

A study reported in the Journal of the American Medical Association involved the study of respiratory tract infections in children aged 1 to 5 years in Israel. During the period November 1999 to March 2000 a randomly selected group of the children received a placebo and another randomly selected group received a mixture of Echinacea and Vitamin C. The following table gives the numbers for the children in each group and for those who developed pneumonia during that time. Treatment:...

A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow (ouch!) using a lightweight plastic snow shovel and an electric snow thrower. Each subject’s heart rate was recorded under the 4 exercise modes. The Excel spreadsheet provides the heart rates for ten subjects under...

A 1992 article in the Journal of the American Medical Association ("A Critical Appraisal of 98.6 Degrees F, the Upper Limit of the Normal Body temperature, and Other Legacies of Carl Reinhold August Wundrlich") reported body temperature, gender, and heart rate for a number of subjects. The temperatures for 25 female subjects follow: 98.0 97.2 97.4 97.6 97.8 97.9 98.0 98.0 98.3 98.1 98.2 98.3 98.3 98.4 98.4 98.4 98.5 98.6 98.6 98.7 98.8 98.8 98.9 98.9 99.0 Test the...

Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow by using a lightweight plastic snow shovel and an electric snow thrower. Each subject's heart rate during snow removal were compared with the values obtained during treadmill and arm-crank ergometer testing. Dataset: HeartRate Treadmill...

Question 2: The Journal of the American Medical Association reported in 2002 on a study of 1,100 airline passengers who flew from San Francisco to Denver. 515 of these passengers traveled on planes where air was re-circulated, the remaining 585 traveled on planes that did not recirculate air. Of those that did travel on planes where the air was recirculated, 110 reported post-flight respiratory problems. Of those on planes that did not recirculate the air, 108 reported post-flight respiratory problems....

Nike’s annual report says that the average American buys 6.5 pairs of sport shoes per year. Suppose the population standard deviation is 2.1 and that a sample of 25 customers will be examined next year. Use this information to determine the following questions based on sampled means: a. What is the standard error of the mean in this experiment? b. What is the likelihood that the sample mean is between 6 and 7 pairs of sports shoes? c. What is...
