Textbook Question
Chapter 10, Problem 54DA
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.

An insurer covers 200 policyholders. The probability that any policyholder will make a claim is 0.2. Let X be the number of policyholders making a claim out of the 200. Using just the cumulative distribution function (cdf), calculate P(35≤X≤55). Give your answer to 4 decimal places.
NOTE: Use R Programming.
1.34 Highly Superior Autobiographical Memory, continued. The researchers in Exercise 1.32 also administered the quiz of past public events to 30 individuals who did not claim to have any unusual memory abilities (controls). Their scores are displayed in Figure 1.17(b), using the same horizontal axis scale as that of the histogram of Figure 1.17(a) for easier comparison.
a. Describe the shape, center, and spread of the distribution of quiz scores for the control individuals. b. Compare the histograms in Figure 1.17(a) and
(b). How does the distribution of scores among the control individuals support your interpretation of HSAM claims from Exercise 1.32(b)?
1.32.b. This histogram suggests that the HSAM claims may be overstated. While some individuals scored very highly on the quiz, others scored only moderately well, and a significant number scored below 60%. This suggests that having HSAM does not necessarily imply perfect or near-perfect recall of autobiographical information. Some…

- 3. Bayesian Inference – Updating Beliefs A medical test for a rare disease has the following characteristics: Sensitivity (true positive rate): 99% Specificity (true negative rate): 98% The disease occurs in 0.5% of the population. A patient receives a positive test result. Questions: a) Define the relevant events and use Bayes’ Theorem to compute the probability that the patient actually has the disease.b) Explain why the result might seem counterintuitive, despite the high sensitivity and specificity.c) Discuss how prior probabilities influence posterior beliefs in Bayesian inference.d) Suppose a second, independent test with the same accuracy is conducted and is also positive.

Linear Regression - Model Assumptions and Interpretation A real estate analyst is studying how house prices (Y) are related to house size in square feet (X). A simple linear regression model is proposed: The analyst fits the model and obtains: • Ŷ50,000+150X YBoB₁X + € • R² = 0.76 • Residuals show a fan-shaped pattern when plotted against fitted values. Questions: a) Interpret the slope coefficient in context. b) Explain what the R² value tells us about the model's performance. c) Based on the residual pattern, what regression assumption is likely violated? What might be the consequence? d) Suggest at least two remedies to improve the model, based on the residual analysis.arrow_forward5.

- 2. Hypothesis Testing - Two Sample Means A nutritionist is investigating the effect of two different diet programs, A and B, on weight loss. Two independent samples of adults were randomly assigned to each diet for 12 weeks. The weight losses (in kg) are normally distributed. Sample A: n = 35, 4.8, s = 1.2 Sample B: n=40, 4.3, 8 = 1.0 Questions: a) State the null and alternative hypotheses to test whether there is a significant difference in mean weight loss between the two diet programs. b) Perform a hypothesis test at the 5% significance level and interpret the result. c) Compute a 95% confidence interval for the difference in means and interpret it. d) Discuss assumptions of this test and explain how violations of these assumptions could impact the results.arrow_forward1. Sampling Distribution and the Central Limit Theorem A company produces batteries with a mean lifetime of 300 hours and a standard deviation of 50 hours. The lifetimes are not normally distributed—they are right-skewed due to some batteries lasting unusually long. Suppose a quality control analyst selects a random sample of 64 batteries from a large production batch. Questions: a) Explain whether the distribution of sample means will be approximately normal. Justify your answer using the Central Limit Theorem. b) Compute the mean and standard deviation of the sampling distribution of the sample mean. c) What is the probability that the sample mean lifetime of the 64 batteries exceeds 310 hours? d) Discuss how the sample size affects the shape and variability of the sampling distribution.arrow_forwardA biologist is investigating the effect of potential plant hormones by treating 20 stem segments. At the end of the observation period he computes the following length averages: Compound X = 1.18 Compound Y = 1.17 Based on these mean values he concludes that there are no treatment differences. 1) Are you satisfied with his conclusion? Why or why not? 2) If he asked you for help in analyzing these data, what statistical method would you suggest that he use to come to a meaningful conclusion about his data and why? 3) Are there any other questions you would ask him regarding his experiment, data collection, and analysis methods?arrow_forward
