- Patrick is studying the relationship between the number of employees per department and the monthly overtime per department and has collected the data shown in the table. The line of best fit for the data is yˆ=0.135x+36.6. Number of Employees 6080100120 Monthly Overtime (Hours) 45475053 According to the line of best fit, what would be the predicted monthly overtime for a department that had 122 employees? Provide your answer below: The predicted monthly overtime is hours.A college bookstore must order books two months before each semester starts. They believe that the number of books that will ultimately be sold for any particular course is related to the number of students registered for the course when the books are ordered. They would like to develop a bestfitting line to predict how many books to order. From past records, the bookstore obtains the number of students registered, X, and the number of books actually sold for a course, Y , for 12 different semesters.A scatterplot of the data along with the best fitting line is presented below. a. The correlation between the two variables is r = .89. Calculate and interpret the value of r2.b. The equation for the best fitting line is Y = 9.30 + 0.673X. Explain and interpret the value of 9.30.c. How many books should the store order for a class of 50 students? Would you trust this prediction?method 1 solve the slope of the trendline y = 0.1078x - 8.0933R² = 0.987 method 2 with the given trendline above let y=10.5, solve for the value of x

- The table shows data collected on the relationship between the average number of minutes spent exercising per day and math test scores. The line of best fit for the data is yˆ=0.44x+65.2. Minutes 25303540 Test Score 76798083 (a) According to the line of best fit, the predicted test score for someone who spent 42 minutes exercising is 83.68. (b) Is it reasonable to use this line of best fit to make the above prediction? Select the correct answer below: The estimate, a predicted test score of 83.68, is both reasonable and reliable. The estimate, a predicted test score of 83.68, is unreliable but reasonable. The estimate, a predicted test score of 83.68, is both unreasonable and unreliable. The estimate, a predicted test score of 83.68, is reliable but unreasonable.The 2011 Tōhoku, Japan earthquake is the newest deadliest earthquake. The power was equal as about 600.000.000 Hiroshima bomb. After the 9.0 magnitude earthquake, 900 aftershocks emerged and around 13,705 casualties had to lose their lives during the course. Because the earthquake so powerful, it has shifted our earth axis by 25 cm. 5. Based on this information, arrive to the conclusion on how much stronger was this earthquake in comparison with 2017 Mexico earthquake. Show work.Accountants at the Tucson firm, Larry Youdelman,CPAs, believed that several traveling executives were submittingunusually high travel vouchers when they returned from businesstrips. First, they took a sample of 200 vouchers submitted from the past year. Then they developed the following multiple-regres-sion equation relating expected travel cost to number of days on the road ( x1 ) and distance traveled ( x2 ) in miles:yn = +90.00 + +48.50x1 + +.40x2The coefficient of correlation computed was .68.a) If Donna Battista returns from a 300-mile trip that took herout of town for 5 days, what is the expected amount she shouldclaim as expenses?b) Battista submitted a reimbursement request for $685. Whatshould the accountant do?c) Should any other variables be included? Which ones? Why?

Transformed equation ln(y) = ln(A) + bx or Y = a + bx.A contractor is planning to bid for a job of filling potholes on a given stretch of a high way. Before approaching for the bid, he decided to have an idea about the road from government agencies. Three departments public works (PW), transport (T) and traffic (Tf),as usual reported, three different average number of potholes in a one KM stretch of the high way. The constant rate of number of potholes per one KM stretch of the high way are 30, 35 and 40 respectively from PW, T and Tf. The contractor believes information from Transport department is more reliable than the other two. The chance that PW will be considered is 1/4, T will be considered is 1/2 and Tf will be considered is 1/4, by the contractor for drawing conclusion. What is the probability of finding exactly three potholes in a randomly selected 100 meter stretch?The intercept is 0, the autoregressive coefficient is 0.2 and the moving average coefficient is 0.5 in an ARIMA(1,1,1) model.
