Week 5 Assignment 1 Chapter 10 Practice Problems |
|
Complete
the problems below from the textbook. You will need to use the "Baseball
2016 Data" and the "Lincolnville School District Bus Data" files
for this assignment.
1. Chapter 10 – Problem 8
At the time she was hired as a server at the Grumney Family Restaurant, Beth Brigden was told, “You can average $80 a day in tips.” Assume the population of daily tips is normally distributed with a standard deviation of $9.95. Over the first 35 days she was employed at the restaurant, the mean daily amount of her tips was $84.85. At the .01 significance level, can Ms. Brigden conclude that her daily tips average more than $80?
2. Chapter 10 – Problem 13
The
mean income per person in the United States is $50,000, and the distribution of
incomes follows a normal distribution. A random sample of 10 residents of
Wilm-ington, Delaware, had a mean of $60,000 with a standard deviation of
$10,000. At the .05 level of significance, is that enough evidence to conclude
that residents of Wilmington, Delaware, have more income than the national
average?
3. Chapter 10 – Problem 53
| Refer to the Baseball 2016 data, which report information on the 30 Major League | |||||
| Baseball teams for the 2016 season. | |||||
| A.) Conduct a test of hypothesis to determine whether the mean salary of the teams was | |||||
| different from $100.0 million. Use the .05 significance level. | |||||
| B.) Using a 5% significance level, conduct a test of hypothesis to determine whether the | |||||
| mean attendance was more than 2,000,000 per team. | |||||
4. Chapter 10 – Problem 54
| Refer to the Lincolnville School District bus data. | |||||||
| A. Select the variable for the number of miles traveled last month. Conduct a hypothesis | |||||||
| test to determine whether the mean miles traveled last month equals 10,000. Use | |||||||
| the .01 significance level. Find the p-value and explain what it means. | |||||||
| B. A study of school bus fleets reports that the average per bus maintenance cost is | |||||||
| $4,000 per year. Using the maintenance cost variable, conduct a hypothesis test to | |||||||
| determine whether the mean maintenance cost for Lincolnville’s bus fleet is more | |||||||
| than $4,000 at the .05 significance level. Determine the p-value and report the | |||||||
| results. | |||||||
