6.27  Average hours per week listening to the radio. The Student Monitor surveys 1200 undergraduates from four-year colleges and universities throughout the United States semiannually to understand trends among college students.11 Recently, the Student Monitor reported that the average amount of time listening to the radio per week was 11.5 hours. Of the 1200 students surveyed, 83% said that they listened to the radio, so this collection of listening times has around 204 (17% × 1200) zeros. Assume that the...

A radio station is selling concert tickets containing a random number from 1-100. Write JAVA program that prompts the user for the number of concert tickets they’d like to purchase. Use a while loop to output each ticket followed by a randomly generated number from 1-100. For example, if the user purchases 3 concert tickets, the output could look like this: Ticket 1: 79 Ticket 2: 19 Ticket 3: 61

A girl of mass, m = 40 kg has osteoporosis which weakens her bones. From a kneeling position, she topples forward onto her elbows with her upper arms extended vertically downwards on impact with the ground. In falling forward, her centre of mass lowers by a height, h = 50 cm and she absorbs all of her kinetic energy from her fall into her two humerus bones (one bone in each upper arm). Determine an equation for the stress in...

A train starts from rest at station A and accelerats at 0.5 m/s^2 for 60s.afterwards it travels with a constant velocity for 15min. It then decelerates at 1m/s^2 until it is brought to rest at station B. Determine the distance between the stations.

A space station is approximately a ring of radius,R, and mass m, which rotates about its symmetry axis with angular velocity,~ω=ω0ˆe3. A meteor is traveling with momentum,~p, that is parallel to the original ˆe3, and strikes the space station at a point on the rim,transferring the entire momentum to the space station (an inelastic collision where the meteor sticks to the space station). Further, though the meteor has significant momentum,it is of very small mass so that the moment of...

Vincent randomly selected a bag of M&Ms from a randomly selected gas station as he was driving down the interstate. Being bored while riding in the car he decided to evaluate his green M&Ms. From the simple random sample there were 19 green M&Ms with a sample mean weight of 0.8635 g any sample standard deviation of 0.0570 g. Use a 0.05 significance level to test the claim that Janine week of all the M&Ms is equal to 0.8535
