Answer #1

The height of the graph is 1/30 minutes.

Because the difference between 4 hours (lower limit of x) and 4 hours 30 minutes (upper limit of x) is 30 minutes.

Since the distribution of arrival times that vary between 4 hours and 4 hours 30 minutes, so the line between 4 hours and 4 hours 30 minutes with the same height as 1/30 minutes.

Let x = the arrival times

The range of x is from 4 hours to 4 hours 30 minutes,

Look the following graph of the above distribution.

Given an airline that flies between two cities with a quoted flight time of 2 hours and 10 minutes (130 minutes). Historical records indicate that the flight time between the two cities varies from 2 hours (120 minutes) to 2 hours and 20 minutes (140 minutes). The flight times are uniformly distributed. What is the probability that the flight will be between 125 minutes and 135 minutes?

Suppose that an airline quotes a flight time of 2 hours, 10 minutes between two cities. Furthermore, suppose that historical flight records indicate that the actual flight time between the two cities, x, is uniformly distributed between 2 hours and 2 hours, 20 minutes. Letting the time unit be one minute, (a) Calculate the mean flight time and the standard deviation of the flight time. (Round your answers to 4 decimal places.) μx σx (b) Find the probability that the...

Consider a packaging/warehousing process with the following steps: 1. The product is filled and sealed. 2. Sealed units are placed into boxes and stickers are placed on the boxes. 3. Boxes are transported to the warehouse to fulfill customer demand. These steps can be combined into a single processing time, as depicted in the system schematic. The system is subject to the following assumptions: 1. There is always sufficient raw material for the process never to starve. 2. Processing is...

JAVA Bike shares are becoming increasingly common in cities in the United States. Commuters have been using bike sharing as a method of transportation for the flexibility, cost savings, exercise, and a myriad of other benefits. While being quite successful, many bike shares are still relatively new and have room for optimization. To help with the optimization process, we want to analyze bike share data from the city of Los Angeles. The first step of the process is to collect...

1. The least squares criterion, SSE, SSR, and SST In the United States, tire tread depth is measured in 32nds of an inch. Car tires typically start out with 10/32 to 11/32 of an inch of tread depth. In most states, a tire is legally worn out when its tread depth reaches 2/32 of an inch. A random sample of four tires provides the following data on mileage and tread depth: Tire Mileage Tread Depth (10,000 miles) (32nds of an...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
