Match the scenario with the appropriate hypothesis test. Each word test may only be used once. Zach has just started running for the first time. He would like to track his mileage with a fitness app on his phone. He finds two apps; one that is free and one that costs money. He doesn’t want to pay money if the apps are equally as good at tracking his mileage. He decides to test the two apps. He chooses 10 routes of varying lengths to which he runs with both tracking apps on during the run. After each run he records the difference in tracked mileage between the apps. What procedure is appropriate to test whether there is an average difference in mileage between the two apps?

a. One Sample z test for a mean b. One sample t test c. One proportion z test d.Matched Pairs t test

The university would like to estimate the proportion of students who used any tobacco product at least once in the last year. They would like to test whether the proportion is more than 50%. From a random sample of 500 students, 276 students said they had used a tobacco product in the last year . What type of procedure is most appropriate for their question of interest?

A construction engineer would like to test whether a large batch of pressure-treated lumber boards are acceptable for use by a given manufacturer. The boards are advertised as 4”x4”x16’ and should weigh 77 lbs. The standard deviation of the boards from the population is 0.16lbs. For the boards to be acceptable there should be no evidence that the boards weigh other than 77 lbs on average. The engineer takes a random sample of 30 boards and finds the average of the sample to be 76.8lbs. What type of test is appropriate for this scenario?

a. One Sample z test for a mean b. One sample t test c. One proportion z test d.Matched Pairs t test

The accompanying table lists the word counts measured from men and women in 56 couple relationships. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables. Use a significance level of

alphaαequals=0.010

The linear correlation coefficient r is ____

(Round to three decimal places as needed.)

Determine the null and alternative hypotheses.

(Type integers or decimals. Do not round.)

The test statistic is ____

(Round to two decimal places as needed.)

The P-value is ____

(Round to three decimal places as needed.)

Because the P-value of the linear correlation coefficient is ___ the significance level, there ____ sufficient evidence to support the claim that there is a linear correlation between words spoken by men and women in couples.

Develop a minimum 700-word analysis of inflation. Include the following:

• Choose a product or service you currently consume/use, such as apparel or educational services, that is included in the CPI's "market basket." Find the annual CPI index numbers for your chosen good or service for the years 1995, 2005, 2010, and 2015. Enter those index numbers in an Excel spreadsheet and calculate the percent change (inflation rates) in those index numbers from 1995 to 2005, from 1995 to 2010, and from 1995 to 2015.  
• Analyze the trends in overall inflation over the last five years and whether your income has kept pace with inflation. How has inflation over the last five years affected you and/or your family?
• Discuss how a business manager, such as a human resources manager, might use CPI statistics.

Write at least a 1-Page Report Open a Word Document

Introduction--Provide a description of your topic and cite where you found your data. Sample Data—Include a 5x10 table including your 50 values in your report. You must provide ALL of your sample data.

Problem Computations—For the topic you chose, you must answer the following: Determine the mean and standard deviation of your sample. Find the 80%, 95%, and 99% confidence intervals. Make sure to list the margin of error for the 80%, 95%, and 99% confidence interval. Create your own confidence interval (you cannot use 80%, 95%, and 99%) and make sure to show your work. Make sure to list the margin of error.

Problem Analysis—Write a half-page reflection. What trend do you see takes place to the confidence interval as the confidence level rises? Explain mathematically why that takes place. Provide a sentence for each confidence interval created in part c) which explains what the confidence interval means in context of topic of your project. Explain how Part I of the project has helped you understand confidence intervals better? How did this project help you understand statistics better?
