13. Using the Empirical Rule of a bell-shaped distribution, approximately what percent of data values lie within two standard deviations of the mean?
1. According to the empirical rule, in a normally distributed set of data, approximately what percent of the scores will be within 1 standard deviation (-1 to +1) away from the mean? 40% 95% 68% 75% 2. f you took an IQ test and your score was 2 standard deviations above average, assuming normal distribution, approximately what percent of all IQ test takers would your score be higher than? 98% 60% 70% 80% 3. if you took an IQ test...
n of 15. Using the empirical rule, what percentage of IQ scores are between 90 and 120
A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 65 months and a standard deviation of 10 months. Using the empirical rule, what is the approximate percentage of cars that remain in service between 85 and 95 months? Do not enter the...
(c) According to the empirical rule, 95% of days in the month
will be between what two temperatures?

Objective 4: Use the Empirical Rule to Describe Data That Are Bell-Shaped 3.2 Measures of Dispersion 3.2.29 0 of 1 Point Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 11. Use the empirical rule to determine thefollowing (a) What percentage of people has an IQ score between 67 and 133? (b) What percentage of people has an IQ score less than 67 or greater...
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 65miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 56 miles per hour and 74 miles per hour. (Assume the data set has a bell-shaped distribution.)
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 7171 miles per hour, with a standard deviation of 33 miles per hour. Estimate the percent of vehicles whose speeds are between 6868 miles per hour and 7474 miles per hour. (Assume the data set has a bell-shaped distribution.)
Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 67 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 61 miles per hour and 73 miles per hour. (Assume the data set has a bell-shaped distribution.)
using minitab, a random sample of 200, (N(30, 8)). 1. According to the empirical rule, how many of the values do you expect to be less than 14 or greater than 46? Briefly explain your answer. 2. Since the weights are distributed N(30, 8), we say that we expect the average weight of a sample of farm-raised turkey to be 30 lbs.; that is, 30 is the expected value (also, the mean) of the distribution. What is the average of...
