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 185.0190 189.9092 185.0149 186.4645 183.9548 188.7506 185.5558 188.3895 186.2233 187.4194 184.1357 185.9834 184.0502 187.1622 184.7336 188.8234 185.3674 187.6940 186.2999 187.2843 185.7915 188.5168 185.2051 191.9938 184.5123 188.7841 185.3354 189.4963 185.7704 187.7137 184.6232 186.3319 185.4893 186.9172 185.5258 189.1875 186.4872 188.5155 186.6961 188.3859 183.5845 189.6209 186.2760 191.2804 184.6890 189.7596 184.0857 187.9947 184.7282 188.8595 184.8456 189.7299 185.5643 188.5457 185.0837 190.4538 184.0496 190.1310 184.9631 189.2649 183.5444 186.3333 186.7199 186.8233 184.6942 187.0778 185.9128 189.8748 185.8872 188.4147 184.6845 191.0355 183.8902 188.2863 183.8863 188.4357 186.0144 188.1452 185.1711 190.1961 186.2472 189.8832
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
