Airline passenger travel light, others heavy. Assume that the weight of the carrry on bags is uniformly distributed between 4 and 24 pounds.
What is median weight of airline bags?
How much would a carry on bag weigh in the 80th percentile?
Computer interquartile weight of carry on bags
A carry on bag weighs 15 pounds . in what quartile is it?
a) Median weight = (4 + 24)/2 = 14
b) Let 80th percentile is x. Then:
(x - 4) / (24 - 4) = 0.80
x - 4 = 16
x = 20
c) 75th percentile:
(x - 4) / (24 - 4) = 0.75
x = 19
(y - 4) / (24 - 4) = 0.25
y = 9
Interquartile weight = 75th percentile - 25th percentile = 19 - 9 = 10
d) Percentile for 15 pounds = (15 - 4) / (24 - 4) = 11/20 = 0.55

Suppose the weight of pieces of passenger luggage for domestic airline flights follows a normal distribution with μ = 26 pounds and σ = 6.7 pounds. (a) Calculate the probability that a piece of luggage weighs less than 31.2 pounds. (Assume that the minimum weight for a piece of luggage is 0 pounds.) (b) Calculate the weight where the probability density function for the weight of passenger luggage is increasing most rapidly. lb (c) Use the Empirical Rule to estimate...
What is the probability that the weight of a bag will be greater than the maximum allowable weight of 50 pounds? Give your answer to four decimal places.Response:Let X represent the weight of a randomly selected bag. For what value of c is P(E(X) - c < X < E(X) + c)=0.91? Give your answer to four decimal places.Response:Assume the weights of individual bags are independent. What is the expected number of bags out of a sample of 12 that...
A (fictional) study finds that airline passenger weigh an average of 185lb with standard deviation of 25b. It also finds they bring an average of 25b of luggage, with a standard deviation of 10b. Assume these weights are independent. If a flight has 180 passengers then: (a) The airline needs to estimate (in advance) the total weight of passengers and their bags. Find the expectation and standard deviation of this. (b) The airline will use this to predict how much...
Suppose that the weight of Florida navel oranges is normally distributed with mean µ = 8 ounces, and standard deviation σ = 1.5 ounces. (a) (1 point) State the model in notation form. (b) (2 points) What proportion of oranges weigh more than 11.5 ounces? (c) (2 points) What proportion of oranges weigh less than 8.7 ounces? (d) (2 points) What proportion of oranges weigh between 6.2 and 7 ounces? Page 3 (e) (5 points) What are the median, mode,...
Jerry has 30 bags of candy. Each bag states that the net weight of the bag is .0469 pounds. Jerry believes that the bags of candy will not all weigh .0469 pounds, so he weighs each bag and writes down the results below. 1) .0466 2) .0471 3).0468 4).0465 5) .0461 6) .0454 7) .0470 8) .0463 9) .0469 10) .0473 11).0462 12) .0468 13) .0469 14).0471 15) .0470 16) .0468 17) .0481 18) .064 19) .0475 20) .0469 21)...
1. The service manager for Air Canada is uncertain about the time needed for the ground crew to turn an airplane around from the time it lands until it is ready to take off. He has been given information from the operations supervisor indicating that the times seem to range between 20 and 45 minutes. Without any further information, the service manager will apply a uniform distribution to the turnaround. (a) Define the density distribution/function. (b) What is the probability...
A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a. What is the distribution for the weights of one 25-pound lifting weight? What is the mean and standard deviation? b. What is the distribution for the mean weight of 100 25-pound lifting weights? c. Find the probability that the mean actual...
SYNOPSIS The product manager for coffee development at Kraft Canada must decide whether to introduce the company's new line of single-serve coffee pods or to await results from the product's launch in the United States. Key strategic decisions include choosing the target market to focus on and determining the value proposition to emphasize. Important questions are also raised in regard to how the new product should be branded, the flavors to offer, whether Kraft should use traditional distribution channels or...
