The quantitative data set under consideration has roughly a bell-shaped distribution. Apply the empirical rule to answer the following question. A quantitative data set has mean 17 and standard deviation 2. Approximately what percentage of the observations lie between 11 and 23? Approximately % of the observations lie between 11 and 23. (Type an integer or a decimal. Round to one decimal place as needed.)

Step 1
The mean is 17 and the standard deviation is 6 (since 17 - 6 = 11 and 17 + 6 = 23). Show more…

The results of a paired-difference test are shown below: a. Construct and interpret a 99% confidence interval estimate for the paired difference in mean values. b. Construct and interpret a 90% confidence interval estimate for the paired difference in mean values. d = -5.7, s = 0.25, n = 25 (Round to two decimal places as needed.)

A certain standardized test's math scores have a bell-shaped distribution with a mean of 525 and a standard deviation of 105. Complete parts (a) (a) What percentage of standardized test scores is between 210 and 840? 99.7 % (Round to one decimal place as needed.) (b) What percentage of standardized test scores is less than 210 or greater than 840? 0.3 % (Round to one decimal place as needed.) (c) What percentage of standardized test scores is greater than 735? % (Round to one decimal place as needed.)

On a test that has a normal distribution, a score of 23 falls two standard deviations below the mean, and a score of 43 falls two standard deviations above the mean. Determine the mean of this test. On a test that has a normal distribution, a score of 84 falls two standard deviations above the mean, and a score of 56 falls two standard deviations below the mean. Determine the mean of this test. On a standardized exam, the scores are normally distributed with a mean of 650 and a standard deviation of 25. Find the z-score of a person who scored 710 on the exam. On a standardized exam, the scores are normally distributed with a mean of 170 and a standard deviation of 20. Find the z-score of a person who scored 220 on the exam.
