An airline is charged by an airport based upon the total taxi-time that an airplane spends to take off and land. Suppose taxi time, a, atairport A is normally distributed with mean of 27 minutes and standard deviation 8 minutes; taxi time, b, at airport B is normallydistributed with mean of 39 minutes and standard deviation 12 minutes; taxi time, c, at airport C is normally distributed with mean of 41minutes and standard deviation 10 minutes. JJ Airlines has a plane flying to airport A, airport B, and airport C on Sunday. Airport Acharges $131 per minute of taxi time; airport B charges $150 per minute of taxi time; airport c charges $200 per minute of taxi time. LetX = total amount of taxi time in minutes for the JJ plane. Let W = total taxi charges for the JJ plane. X is defined as X = a + b + c. W =131a + 150b + 200c. Note that a, b, and c are independent of one another.c) Calculate the expected value of W. 17587d) Calculate the standard deviation of W.e) If we pick a value k such that the probability that X > k equals .25 then calculate k?f) JJ Airlines has $20,000 available to pay for taxi time? What is the probability that JJ has enough to pay the total taxi time bill onSunday?Please solution USING R script

6. Medical researchers conducted a study to determine whether treadmill exercise could improve the walking ability of patients suffering from claudication, which is pain caused by insufficient blood flow to the muscles of the legs. A sample of 51 patients walked on a treadmill for six minutes every day. After six months, the mean distance walked in six minutes was 370 meters, with a standard deviation of 83 meters. For a control group of 41 patients who did not walk on a treadmill, the mean distance was 330 meters with a standard deviation of 84 meters. Can you conclude that the mean distance walked for patients using a treadmill differs from the mean for the controls? Let μ1 denote the mean distance walked for patients who used a treadmill. Use the =α0.01 level of significance and the TI-84 Plus calculator. please list all 6 steps of the p method clearly

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed with a mean of 8 million dollars and a standard deviation of 1.3 million dollars. One health care information systems company considers a quarter a "fallure" if its sales level that quarter is in the bottom 10% of all quarterly sales levels. Determine the sales level (in millions of dollars) that is the cutoff between quarters that are considered "failures" by that company and quarters that are not.

Fast Auto Service provides oil and lube service for cars. It is known that the mean time taken for oil and lube service at this garage is 15 minutes per car and the standard deviation is 2.4 minutes. The management wants to promote the business by guaranteeing a maximum waiting time for its customers. If a customer's car is not serviced within that period, the customer will receive a 50% discount on the charges. The company wants to limit this discount to at most 3% of the customers. What should the maximum guaranteed waiting time be? Assume that the times taken for oil and lube service for all cars have a normal distribution.Round your answer to the nearest minute.
The speed of cars driving past Johnson City High School, on 666 Reynolds Rd, were recorded over one school year. The speed limit on that part of Reynolds Rd is 20 mph. The mean of the speed readings was 24.19 mph, with a standard deviation of 3.56 mph.
The mean number of time taken by MBA-B05 students to complete their project is 40 hours with a standard deviation of 2.93 hours. a) If the data are approximately normally distributed, between what two numbers would 95% of the values fall? b) If the distribution is unknown between what two numbers would approximately 88.89% of the values fall?
In Mr Samboko courses, the coeﬃcient of correlation between General biology I and General-biology II for 20 students is 0.3, Mean of General biology I and General-biology II are 15 and 20 respectively and also the standard deviation of General biology I and General-biology II are 4 and 5 respectively. At the time of calculation one item 27 has wrongly been taken as 17 for General biology I and 35 instead of 30 for General biology II. As a biostatistics student ﬁnd the correct coeﬃcient of correlation between General biology I and General-biology II for 20 students.
Suppose that on a certain section of I-95, with a posted speed limit of 65 miles per hour, the speeds of all vehicles have a bell-shaped distribution with a mean of 72 mph and a standard deviation of 3 mph. Find the percentage of vehicles with the following speeds on this section of I-95: greater than 75 mph.
The human resources department of a consulting firm gives a standard creativity test to a randomly selected group of new hires every year. This year, 100 new hires took the test and scored a mean of 113.6 points with a standard deviation of 134. Last year, 95 new hires took the test and scored a mean of 116.4 points with a standard deviation of 16.8. Assume that the population standard deviations of the test scores of all new hires in the current year and the test socores of all new hires last year can be estimated by the sample standard deviations, as the samples used were quite large. Construct a 90 confidence interval for the difference between the mean test score , of new hires from the current year and the mean test score , of new hires from last year. Then tind the lower limit and upper limit of the 905% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answeis to at least two decimal places.
