Task I: Two teams (A and B) at Ferrari company are trying to develop the best California T for this project. Your supervisor asked you to compare two different samples of each team. You need to examine a sample of 50 cars from each group and measure their maximum speed. Use the results shown in table 1 below to determine the following: What is the mean, mode, median, and standard deviation of maximum speeds for each group of cars? Divide each data group into four categories and create the frequency table for each category. Calculate the mean and standard deviation from the frequency tables and compare to results found in part a. Present the data as a histogram. Present the data as frequency polygon Table 1 Team A Team B Maximum Speed (mph) 185.3220 187.8136 185.1793 184.4689 187.0496 186.9742 184.2262 189.5322 185.4633 188.7326 185.6820 190.9942 183.4812 188.9213 185.6793 186.0114 186.6068 191.8264…

The toll plaza on Route 1 in Dover has four tollbooths open to all vehicles. Ms. Timlin conducted a chi-square goodness of fit test to see if all of the booths are used in equally. A chi-square value of 23.4 was calculated, resulting in a p-value of 0.006. Which of the following is correct? a. There is sufficient evidence to suggest that the tollbooths are not used in equal proportions. Selected:b. There is sufficient evidence to suggest that the tollbooths are used in equal proportions.This answer is incorrect. c. The tollbooths are used in equal proportions. d. There is insufficient evidence to suggest that the tollbooths are used in equal proportions. e. There is insufficient evidence to suggest that the tollbooths are not used in equal proportions.

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material. Compute the values below (to 2 decimals, if necessary). Sum of Squares, Treatment Sum of Squares, Error a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05.
