A highway department executive claims that the number of fatal accidents which occur in her state does not vary from month to month. The results of a study of 169 fatal accidents were recorded. Is there enough evidence to reject the highway department executive's claim about the distribution of fatal accidents between each month?

A statistical program is recommended. Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Weekly Usage(hours) AnnualMaintenanceExpense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0 #1) Develop the estimated regression equation that could be used to predict the annual maintenance expense (in hundreds of dollars) given the weekly usage (in hours). (Round your numerical values to two decimal places.) #2) The expected expense of a machine being used 34 hours per week is $ hundred.
In the macro relation between GDP and FDI, Dr Mudenda obtained the following valuesfrom a Stata output: FDI coefficient of 0.45; t-statistic of 3; and covariance (GDP, FDI)value of 0.41. In literature, this relationship between GDP and FDI has generally beenestablished to be statistically significant. Answer the following questions:i) Calculate the variance of the FDI variable and explain its implicationii) Use the confidence interval approach to test whether FDI’s influence on GDP isstatically significant or not in Dr Mudenda’s study. Use 5% level which gives 1.96critical values.iii) What is the expected value of the p-values for studies that have been conductedin literature?
The management of Brinkley Corporation is interested in using simulation to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows: ProcurementCost ($) Probability Labor Cost ($) Probability TransportationCost ($) Probability 10 0.25 20 0.10 3 0.75 11 0.45 22 0.25 5 0.25 12 0.30 24 0.35 25 0.30 Why is the simulation approach to risk analysis preferable to generating a variety of what-if scenarios? Management believes the project may not be sustainable if the profit per unit is less than $5. Use simulation to estimate the probability the profit per unit will be less than $5. If required, round your answer to two decimal places.
Suppose a paint manufacturer has a daily production, x, that is normally distributed with a mean of 100,000 gallons and a standard deviation of 10,000 gallons. Management wants to create an incentive bonus for the production crew when the daily production exceeds the 90th percentile of the distribution, in hopes that the crew will, in turn, become more productive. At what level of production should management pay the incentive bonus?

Habitt is a fine home and interior design store located in Karachi, Pakistan, that specializes primarily in art and science of understanding people's behaviour to create functional spaces within a building and to decorate using their ideas. The company recently became interested in determining the likelihood of one of its designing portfolios being selected to be sold within a certain number of days. An analysis of company sales of 700 portfolios in previous years produced the following data. Table 4.1 Days until Portfolio is selected to be Sold Less than 30 41-70 Greater than 80 Less than $60K 20 50 90 $60-$120K 40 100 270 $120-$180K 40 80 130 Greater than $ 180K 20 10 20 Assuming that a contract was just signed to select a portfolio with an initial asking price of less than $60K, what is the probability that the portfolio will take Ideal Home more than 80 days to sell?
(a) A generic brand of the anti-histamine Diphenhydramine markets a capsule with a 50 milligram dose. The manufacturer is worried that the machine that fills the capsules has come out of calibration and is no longer creating capsules with the appropriate dosage. Research Question: Does the data suggest that the population mean dosage of this brand is different than 50 mg? Is this a one-tail test or two tail test? If one tail, state if it is right tail or left tail. (b) After receiving complaints from McDonald’s customers in Japan about the amount of french fries being served, the on-line news magazine ”Rocket News” decided to test the actual of the fries served at a particular Japanese McDonald’s restaurant. According to the Rocket News article, the official weight standard set by McDonald’s of Japan is for a medium sized fries to weigh 120 grams. The publication weighed the fries from 25 different medium fries they purchased and found the average weight of the fries in their…
