Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 6 hours of burning, a candle has a height of 18.6 centimeters. After 21 hours of burning, its height is 12.6 centimeters. What is the height of the candle after 13 hours?
Suppose that the height (in centimeters) of a candle is a linear function of the amount of time in hours) it has been burning. After 11 hours of burning, a candle has a height of 19.8 centimeters. After 26 hours of burning, its height is 16.8 centimeters. What is the height of the candle after 19 hours? Candle height (in cm) O centimeters X 5 ? Burning time (in hours)
Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 14 hours of burning, a candle has a height of 20.6 centimeters. After 30 hours of burning, its height is 11 centimeters. What is the height of the candle after 26 hours?

Suppose that the weekly amount of down time in hours, Y, for an industrial machine follows a Gamma distribution with mean lb = aß = 2ß, where B is an unknown parameter. The weekly loss in dollars, X, to the industrial operation as a result of this down time is given by X = 3Y + 30. Based on a sample of n observations, find an unbiased estimator for of as a function of the statistic y.
The mean height of a certain kind of plant is 175 centimeters. Suppose we want to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 175. State the null hypothesis Ha and the alternative hypothesis H, that we would use for this test. n
16. The equation models the height h in centimeters after i seconds of a weight attached to the end of a spring that has been stretched and then released a Solve the equation for t
4. The amount of time T (in hours) that a certain electrical component takes to fail has an exponential distribution with parameter > 0. The component is found to be working at midnight on a certain day. Let N be the number of full days after this time before the component fails (so if the component fails before midnight the next day, N = 0). (a) What is the probability that the component lasts at least 24 hours? (b) Find...

The average height of females in a population of a certain college has been 162 centimeters with a population standard deviation of 7 centimeters. Is there a reason to believe that there has been a change in the average height if a random sample of 49 females in the present freshman class has an average height of 166 centimeters? Use a 0.01 level of significance. Answer each part separately. PART A: Is this a z test or t test? *...
