**Is CEO Compensation Related to a Company's Performance?**To test whether CEO compensation and a company's stock performance are related, a financial analyst collected data on 15 randomly selected, publicly traded companies. The analyst examined two variables: the percent change in stock price over the past five years (denoted as $ x $) and the percent change in CEO compensation over the past five years (denoted as $ y $). For these 15 companies, the least-squares regression equation relating the two variables was $ \hat{y} = -0.161 + 0.039x $, and the standard error of the slope of this least-squares regression line was approximately 0.018.Using this information, perform a hypothesis test for a significant linear relationship between these two variables regarding the population slope $ \beta_1 $. Assume that the variable $ y $ follows a normal distribution for each value of $ x $ and that the other regression assumptions are satisfied. Use the 0.10 level of significance and perform a two-tailed test. Complete the parts below:- (a) State the null hypothesis $ H_0 $ and the alternative hypothesis $ H_1 $. $ H_0 :\ $ ( ) $ H_1 :\ $ ( )- (b) Determine the type of test statistic to use. (Choose one)- (c) Find the value of the test statistic. (Round to three or more decimal places.)- (d) Find the two critical values at the 0.10 level of significance. (Round to three or more decimal places.)**Note:** If necessary, consult a list of formulas.**Graphical Explanation:**- The regression plot would typically show the relationship between $ x $ (percent change in stock price) and $ y $ (percent change in CEO compensation) with the regression line based on the given equation, indicating any correlation trends.- The equation $ \hat{y} = -0.161 + 0.039x $ can be used to predict changes in CEO compensation based on stock price changes.- Standard errors help determine the reliability of the slope estimate, which is tested in hypothesis testing to see if there is a significant relationship between the variables. ### Statistical Hypothesis Testing: An OverviewIn this exercise, we will perform a two-tailed test to determine the linear relationship between two variables. Here are the steps and components involved:#### (a) Hypotheses Formulation- **Null Hypothesis ($ H_0 $)**: The statement assuming no effect or no difference.- **Alternative Hypothesis ($ H_1 $)**: The statement we aim to prove, indicating an effect or difference.#### (b) Test Statistic- **Type of Test Statistic**: Select the appropriate test statistic to analyze the data. Choices may include t-test, z-test, chi-square, etc., depending on the data and hypotheses.#### (c) Calculating the Test Statistic- **Value of the Test Statistic**: Calculate this value from the data, rounding to three or more decimal places for precision.#### (d) Critical Values- **Critical Values at 0.10 Level of Significance**: Determine the threshold values for the test statistic, rounded to three or more decimal places, to decide whether to reject $ H_0 $.#### (e) Conclusion- **Conclusion Based on the 0.10 Level**: Analyze if there is a significant linear relationship between the percent change in stock price and CEO compensation over the past five years. - Options: **Yes** or **No**### Symbols and Calculator FunctionsThe diagram on the right provides mathematical symbols and tools for calculations, such as mean ($\bar{x}$), standard deviation ($\sigma$), greater than or less than ($>, <$), and equality/inequality ($=, \neq$).Remember: When filling in the blanks or selecting from options, ensure the correctness based on the problem's context and available data. Make well-informed decisions using statistical principles.

Consider a linear regression model that relates school expenditures and family background to student performance in Massachusetts using 224 school districts. The response variable is the mean score on the MCAS (Massachusetts Comprehensive Assessment System) exam given in May 1998 to 10th-graders. Four explanatory variables are used: (1) STR is the student-to-teacher ratio, (2) TSAL is the average teacher’s salary, (3) INC is the median household income, and (4) SGL is the percentage of single family households. The Excel Regression output for the sample regression equation is given below. (a) What proportion of the variation in MCAS score is explained by the explanatory variables? (b) At the 5% level, are the explanatory variables jointly significant in explaining MCAS score? Explain briefly. (c) At the 5% level, which variables are individually significant at predicting MCAS score? Explain briefly. (d) Suppose a second regression model (Model 2) was generated using only…

Hiroshi Sato, an owner of a sushi restaurant in San Francisco, has been following an aggressive marketing campaign to thwart the effect of rising unemployment rates on business. He used monthly data on sales ($1,000s), advertising costs ($), and the unemployment rate (%) fromJanuary 2008 to May 2009 to estimate the following sample regression equation: Sales(t) = 17.51 +0.05 Advertising Costs(t-1) – 0.70 Unemployment Rate t-1 Requirement: a. Hiroshi had budgeted $620 toward advertising costs in May 2009. Make a forecast in June2009, if the unemployment rate in May 2009 was 9.1%b.

Biologist Theodore Garland, Jr. studied the relationship between running speeds and morphology of 49 species of cursorial mammals (mammals adapted to or specialized for running). One of the relationships he investigated was maximal sprint speed in kilometers per hour and the ratio of metatarsal-to-femur length. A least-squares regression on the data he collected produces the equation ŷ = 37.67 + 33.18x %3D where x is metatarsal-to-femur ratio and ŷ is predicted maximal sprint speed in kilometers per hour. The standard error of the intercept is 5.69 and the standard error of the slope is 7.94. Construct an 80% confidence interval for the slope of the population regression line.
