Air-USA has a policy of booking as many as 24 persons on an airplane that can seat only 22. Past studies have revealed that only 88% of the booked passengers actually arrive for the flight.) Find the probability that if Air-USA books 24 persons, not enough seats will be available. prob - Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less Ono, it is not low...

A student at a junior college conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, x, and grade-point average, y. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is y = -0.0516x + 2.9389 (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade-point average...

The Student Recreation Center wanted to determine what sort of physical activity was preferred by students. In a survey of 95 students, 62 indicated that they preferred outdoor exercise over exercising in a gym. When estimating the proportion of all students at the university who prefer outdoor exercise with 99% confidence, what is the margin of error?

1. In an August 2012 Gallup survey of 1,012 randomly selected U.S. adults (age 18 and over), 53% said that they were dissatisfied with the quality of education students receive in kindergarten through grade 12. The bootstrap distribution (based on 5,000 samples) is provided. a). Would it be appropriate to use the normal distribution to construct the confidence interval in this situation? Explain briefly. b). The standard error from the bootstrap distribution is SE = 0.016. Use the normal distribution...
