It is estimated that Old Faithful geyser in Yellowstone National Park erupts every 90 minutes. One day was selected at random and the times of Old Faithful’s eruptions were recorded. The number of minutes between eruptions is recorded below. Can you conclude that the mean time between eruptions differs from 90 minutes? The number of minutes between eruptions are: 93, 94, 91, 88, 99, 89, 94, 96, 76, 109, 94, 96, 91, 98, 96 What is the test value? Round...

3. The U.S. Geological Survey compiled historical data about Old Faithful Geyser (Yellowstone National Park) from 1870 to 1987. Let x1 be a random variable that represents the time interval (in minutes) between Old Faithful eruptions for the years 1948 to 1952. Based on 9,800 observations, the sample mean interval was 62.6 minutes. Let x2 be a random variable that represents the time interval in minutes between Old Faithful eruptions for the years 1983 to 1987. Based on 24,404 observations,...

A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...
