A study was conducted to see whether heart rate (y) on swimmers linearly related to their age (x1) and swimming time for 2000 meters (x2). A random sample of ten swimmers was selected and the result is shown in the following Microsoft Excel output. (a) Interpret the value of R2 from the output. (b) Conduct a hypothesis test to test whether the linear regression model is fit or not using a = 0.05. (c) Calculate the 95% confidence interval for the coefficient value for age

Food deserts have become a particularly hot topic in the public health community as an explanation for a variety of negative health outcomes in disadvantaged areas. A researcher is interested in comparing the average shelf space provided by supermarkets, convenience stores, and corner stores in two different communities in order to address the growing concern for food deserts. Assume the following table reports the summary statistics for shelf space dedicated to fresh fruits and vegetables (meters) from SRSs of a variety of different stores that supply groceries from each community. Community Average shelf space for fresh fruits and vegetables (m) Sample standard deviation Sample size "Food desert" 13.7 2.4 12 Other community 89.4 14.6 14 A) Carry out the appropriate statistical test in order to determine if there is a significantdifference in mean shelf space between the two communities at the alpha level of 0.05.

Profitability remains a challenge for banks and thrifts with less than $2 billion of assets. The business problem facing a bank analyst relates to the factors that affect return on assets (ROA), an indicator of how profitable a company is relative to its total assets. Data collected from a sample of 194 community banks include the ROA (%), the efficiency ratio (%), as a measure of bank productivity (the lower the efficiency ratio, the better), and total risk-based capital (%), as a measure of capital adequacy. A multiple linear regression model resulted in an SSR of 5.25 and an SSE of 125.02. Calculate the test statistic. FSTAT=____________ (Round to two decimal places as needed.)

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).
