Hello, i need help with questions , 6 & 8

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 the following. (a) What percentage of people has an IQ score between 89 and 111? (b) What percentage of people has an IQ score less than 89 or greater than 111? (c) What percentage of people has an IQ score greater than 111? (a) :|% (Type an integer or a decimal.) (b) :|% (Type an integer or a decimal.) (c) :|% (Type an integer or a decimal.) According to the U.S. Census Bureau, the mean of the commute time to work for a resident of Seattle, Washington is 29.8 minutes. Assume that the standard deviation of the commute time is 4.9 minutes to complete parts (a) through (c). (a) What minimum percentage of commuters in Seattle has a commute time within 3 standard deviations of the mean? DVD (Round to one decimal place as needed.) (b) What minimum percentage of commuters in Seattle has a commute time within 1.5 standard deviations of the mean? What are the commute times within 1.5 standard deviations of the mean? The minimum percentage of commuters in Seattle that has a commute time within 1.5 standard deviations of the mean is D%. (Round to one decimal place as needed.) The commute times within 1.5 standard deviations of the mean are between El and El minutes. (Type integers or decimals. Do not round. Use ascending order.) (c) What is the minimum percentage of commuters who have commute times between 20 minutes and 39.6 minutes? % (Round to one decimal place as needed.)
