Yolanda Gonzales owns and manages a small business in San Francisco, California. The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Yolanda provides incentives for the four salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Below is a chart giving a summary of the information that Yolanda has to work with. (In the chart, a "sample" is a collection of daily sales figures, in dollars, from this past year for a particular salesperson.)

You are playing a dice game with a friend and become suspicious that he is using weighted dice. So you stop the game, take one of his dice, and roll it 100 times. The results are in the table below. Do these results provide significant evidence that the proportion of times the dice lands on the six numbers are unequal? Calculate the chi-squared test statistic and the range the p-value falls in for this test. Number on die 1 2 4 Frequency 16 21 6 26 13 18 test statistic = 14.12, p-value in (.01, .025) test statistic = 24.368, p-value in (.005, .01) test statistic = 14.12, p-value in (.025, 05) test statistic = 24.368, p-value less than .005 O none of these

IQ scores for three different blood lead levels was measured. If we use three categories of blood lead levels with measured verbal IQ scores, we get the computer output which is summarized in table form. Using a 0.05 significance test, test the claim that the three categories of blood lead level have the same mean verbal IQ score. Does exposure to lead appear to have an effect on verbal IQ scores? Interpret the table below. Source of variation df Sum of squares Mean squares Computed f p-value LEAD 2 142 71 0.39 0.677 Error 118 21441 182 Total 120 21584
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…
