To find: The mean time that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight.

Answer to Problem 1CQQ

The mean time that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight is 14min.

Explanation of Solution

Given info: The data shows that the times that American Airlines flights used to taxi to the Los Angeles terminal after landing from a flight.

Calculation:

The formula for mean is,

x¯=xn

Mean time is,

x¯=12+8+21+17+125=705=14

To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer’s adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

K The mean height of women in a country (ages 20-29) is 63.7 inches. A random sample of 65 women in this age group is selected. What is the probability that the mean height for the sample is greater than 64 inches? Assume σ = 2.68. The probability that the mean height for the sample is greater than 64 inches is (Round to four decimal places as needed.)
In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.6 inches and a standard deviation of 4.0 inches. A study participant is randomly selected. Complete parts (a) through (d) below. (a) Find the probability that a study participant has a height that is less than 68 inches. The probability that the study participant selected at random is less than 68 inches tall is 0.4. (Round to four decimal places as needed.) 20 2
