Tips given to taxi drivers form a substantial part of their income. They also serve as a loose metric of service quality that can be useful for taxi companies. An analysis of a large dataset shows that the tips given (as a percentage of taxi fares) are normally distributed with mean 21.3% and standard deviation 7.5%. Furthermore, tips received for different trips are independent from each other. taxi driver expects to do 2000 trips next year. For approximately how many of these trips will he receive a tip over 25%?

instructor thinks that the mean score is higher. She samples 10 statistics students and obtains the scores: Grades 63.9 68.4 | 69 | 96 64.3 | 63.9 65 69 62.7 68.4 Test grades are believed to be normally distributed. Use a significance level of 5%. A. State the alternative hypothesis: HA: Ou + 65 Ομ 65 B. State the mean of the sample: C. State the standard error of the sample means:
Consider the following sample data. Sample A: 5, 8, 11 Sample B: 64, 67, 70 Sample C: 1,015; 1,018; 1,021 (a) Find the mean and standard deviation for each sample. (b) What does this exercise show about the standard deviation? multiple choice The idea is to illustrate that the standard deviation is not a function of the value of the mean.

Autopitch devices are made for both major- and minor-league teams to help them improve their batting averages. When set at the standard position, Autopitch can throw hardballs toward a batter at an average speed of 53 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 9 devices at a time. The average range is 4 mph. a) Using this information, construct control limits for the x-chart. UCL,-mph (round your response to three decimal places).

In Country A, the population mean height for 3-year-old boys is 37 inches. Suppose a random sample of 15 3-year-old boys from Country B showed a sample mean of 36.8 inches with a standard deviation of 2 inches. The boys were independently sampled. Assume that heights are Normally distributed in the population. Complete parts a through c below. a. Determine whether the population mean for Country B boys is significantly different from the Country A mean. Use a significance level of 0.05. Which of the following correctly states Ho and Ha?
