You may need to use the appropriate technology to answer this question. Suppose data made available through a health system tracker showed health expenditures were $10,349 per person in the United States. Use $10,348 as the population mean and suppose a surve research firm will take a sample of 100 people to investigate the nature of their health expenditures. Assume the population standard deviation is $2,500 (a) Show the sampling distribution of the mean amount of health care expenditures in dollars for a sample of 100 people 250 0 500 250 250 00 5048 10098 10348 10598 10846 @O -500-250 300 250 0

In your work as a biomedical engineer, you need to better understand the distribution of adults' blood pressures. Specifically, you are interested in systolic blood pressure, which is a measure of pressure within arteries when a heart beats; this is the first number in a blood pressure reading. In healthy adults, systolic blood pressure has a normal distribution with a mean of 112 mm Hg and standard deviation of 10 mmHg. Before you collect sample data, you want to predict the range in which you expect almost all of the data to fall. Which of the following represents the interval that will likely contain almost all (~99.7%) of the sample measurements of healthy adult systolic blood pressure? A) (102 mm Hg, 122 mm Hg) B) (92 mm Hg, 132 mm Hg) C) (82 mm Hg, 142 mm Hg) D) (72 mm Hg, 152 mm Hg)

A quantitative data set has size 50. At least how many observations lie within three standard deviations to either side of the mean?

Think of your own example of a data set that would follow a normal distribution and explain why.

According to the U.S. Census, the average adult woman is the United States is 65 inches tall and the standard deviation is 3 inches.  If Zsike is 67 inches tall, what is her z-score?

Answer the following question from the distribution represented bythe histogram below. How much can there be at most data that is smaller thanthe median estimate ?

The hotel room rate in Miami, Florida is normally distributed with a mean of $286 per night. Assume that the standard deviation is unknown.  If 19% of the Miami hotel room rates are more than $300 per night, what is the variance?

what measure of variability is to be computed with a median

As reported in Runner's World magazine, the times of the finishers in the New York City 10- km run are normally distributed with mean 61 minutes and standard deviation 9 minutes. The 75th percentile for the finishing times is 67 minutes. What is the interpretation of this value?
