A large company employs workers whose IQs are distributed normally with mean 110 and standard deviation 7.5. Management uses this information to assign employees to projects K that will be challenging, but not too challenging. What percent of employees would have IQs between 107 and 119? Click here to see page 1 of the table for areas under the standard normal curve. Click here to see page 2 of the table for areas under the standard normal curve. The percentage of employees who would have IQs between 107 and 119 would be % (Round to the nearest tenth as needed.) In nutrition, the recommended daily allowance of vitamins is a number set by the government to guide an individual's daily vitamin intake. Actually, vitamin needs vary drastically from person to person, but the needs are closely approximated by a normal curve. To calculate the recommended daily allowance, the government first finds the standard deviation and the average need for vitamins among people in the population. The recommended daily allowance is then defined as the mean plus 27 times the standard deviation. What fraction of the population will receive adequate amounts of vitamins under this plan?

The fraction of the population that will receive adequate amounts of vitamins under the given plan is |. (Type an integer or decimal rounded to the nearest thousandth as needed.) K The times taken by workers to assemble a certain kind of cell phone are normally distributed with mean 19.0 minutes and a standard deviation 3.8 minutes. Find the probability that one such phone will require less than 13.3 minutes in assembly. Click here to see page 1 of the table for areas under the standard normal curve. Click here to see page 2 of the table for areas under the standard normal curve. The probability that a phone will require less than 13.3 minutes in assembly is (Round to three decimal places as needed.)
