please answer within 30 minutes. Maaño Auto Tire sells all types of tires, but a popular radial tire accounts for a large portion of Jeric overall sales.Recognizing that inventory costs can be quite high with this product, Jeric wishes to determine a policy for managing thisinventory. To see what the demand would look like over a while, he wishes to simulate the daily demand for several days.Using the table of random numbers, choose 10 samples starting from 151 and in the fifth column.Demand for TiresFrequency (Days)0201852120532616345••●

We need to simulate the Demand for tires using a random number table. Let us assume that each of the…

The marketing department at Skywalker Inc. has just realized that its competitor, VaderEnterprises, has started producing a rival product, RedSaber. Because both productscompete directly for the same consumer segment, the combined demand (i.e., the sum)of BlueSaber and RedSaber remains normally distributed with mean 100 and standarddeviation 20. The demand for BlueSaber is now a random fraction of this total demand;with the remainder of total demand going to RedSaber. This random fraction is either0.3 or 0.9 with equal probability, and this random fraction is statistically independent ofthe total demand for both BlueSaber and RedSaber. (i.) What is the expected demand for BlueSaber? (ii.) What is the probability that the demand for BlueSaber is less than 40?
A personal trainer wanted to test the effectiveness of two different workout routines. She took a random sample of 70 of her clients and, in a random order, had them complete one of the two routines for two weeks. Then, after a one-month waiting period, she asked them to come back and do the other routine for two weeks. After each two-week period of the exercise routines, she measured their performance on a physical fitness aptitude test. She found the average difference in aptitude scores between the two routines for each client was 30.4 with a standard error of 3.2. What would be her 85% confidence interval for the average difference in the effectiveness of the two routines? (3 decimal places) ( , )
A pet food producer manufactures and then fills 25-pound bags of dog food on two different production lines located in separate cities. In an effort to determine whether differences exist between the average fill rates for the two lines, a random sample of 19 bags from line 1 and a random sample of 23 bags from line 2 were recently selected. Each bag’s weight was measured and the following summary measures from the samples were reported: Production Line 1 Production Line 2 Sample Size, n 19 23 Sample Mean, x 24.96 25.01 Sample Standard Deviation, s 0.07 0.08 Management believes that the fill rates of the two lines are normally distributed with equal variances. a) Calculate the point estimate for the difference between the population means of the two lines. b) Develop a 95% confidence interval…
A statistician wants to determine if there is a difference in the fuel efficiency of cars between model years. To do this, he selects random makes and models of cars and compares the fuel efficiency in miles per gallon of the current model year and the previous model year. Suppose that data were collected for a random sample of 9 cars, where each difference is calculated by subtracting the fuel efficiency in miles per gallon of the previous model year from the fuel efficiency in miles per gallon of the current model year. Assume that the fuel efficiencies are normally distributed. What type of test is this hypothesis test? A. This is a two-tailed test because the alternative hypothesis is Ha:μd≠0. B. This is a right-tailed test because the alternative hypothesis is Ha:μd>0. C. This is a right-tailed test because the alternative hypothesis is Ha:μd<0. D. This is a left-tailed test because the alternative hypothesis is Ha:μd<0. E. This is a left-tailed…
A community college professor is interested in determining the relationship between the number of posts students make on Schoology and their respective grades. He planned to correlate the results from a sample from all his classes, however, due to time constraints, he decided to sample only from students with high grades. As his statistical consultant, state whether or not you support his plans and why.
After being hired as a financial advisor for a large real estate company, you have been tasked with exploring trends between home size (square ft) and property taxes to see if a relationship exists and if that trend can be applied outside of just the sample data. In the Excel Lab #5 Data File, you will find raw data on sheet 1. However, to simplify your calculations, you have only been asked to test a random sample of 10 homes. So, your first step will be to randomly select data from 10 of the homes and paste them into sheet 2 called “sample data”. This will be the data that you will analyze. (You can generate 10 random numbers between 5 and 30 however you want for your sample, but know that there is essentially no chance two students should have the same 10 samples). Within the Excel spreadsheet, use the Excel tools/functions to calculate the correlation coefficient, test statistic, and p-value. You will also use Excel to generate a scatterplot of your sample data with a linear…
