The selling price of new homes in a city over a year was normally distributed with a mean of $115,000 and a standard deviation of $25,000. A random sample of 16 new home sales from this city was taken. Describe the sampling distribution of the sample mean (indicate center, spread, shape). mean = $115,000, standard deviation = $6,250, and shape = exactly normal mean = $115,000, standard deviation = $2,500, and shape = exactly normal mean = $115,000, standard deviation = $25,000, and shape = exactly normal mean = $115,000, standard deviation = $6,250, and shape=unknown O mean = $115,000, standard deviation = $2,500, and shape = approximately normal by the Central Limit Theorem

A normal distribution has a mean of 62 and a standard deviation of 17. What is the median?

The scores of individual students on the American College Testing (ACT), a college readiness assessment, have a Normal distribution with a mean of 18.6 and a standard deviation of 6.0. At Northside High, 36 seniors take the test. Assume the scores at this school have the same distribution as national scores. What is the mean of the sampling distribution of the sample mean score for a random sample of 36 students? 0 1 0 6

The highway mileage (mpg) for a sample of 8 different models of a car company can be found below. Find the mean, median, mode, and standard deviation. Round to one decimal place as needed. Use technology.20, 22, 26, 27, 29, 32, 33, 33Mean = Median = Mode = Standard Deviation =

Most medical schools require applicants for admission to take the Medical College Admissions Test (MCAT) examination. Scores on the MCAT are roughly normally distributed with a mean of 500 and a standard deviation of 10.6. What percentage of students score above 518 points? ( write as a decimal and round to the nearest hundredth)

A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 901 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.85 hours with a standard deviation of 0.57 hour. Complete C and D.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 68 miles per​ hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour.​ (Assume the data set has a​ bell-shaped distribution.) Approximately nothing​% of vehicles travel between 65 miles per hour and 71 miles per hour.
