(b) What is the probability the sample mean will be within $100 of the population meen? (Round your answer to four decimal places)(c) What is the probability the sample mean will be greater than 817.4007 (Round your answer to four decimal places)If the survey research firm reports a sample mean greater than $12,400, would you question whether the firm followed correct sampling procedures? Why or why not?Yes, because $12,400 is not within $100 of the population meanO No, because $12,400 is within one standard deviation of $10,348OYes, because the probability that the sample mean will be greater than $12,400 is very smalO No, because the probability that the sample mean wibbe greater than $12,400 is very largeNeed Help?Not 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 surveyresearch 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 people230534802503002307048 10348 12848 15348LA-500-250@O9048 10098 10348 10598 10545250X

According to the U.S. Census Bureau, the average household income was $73,298 in 2014 (the latest year for which complete data is available). The median household income in 2014 was $53,719.

Which measure do you think better captures the central tendency (or lay person’s sense of “average”) of the distribution of income in this country?

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)
