A website that rents movies online recorded the age and the number of movies rented during the past month for some of their customers. The data are shown below for a random sample of 25 of their customers.The regression line for the data, with number of movie rentals as the response variable, provides an intercept = 18.87, and slope = -0.228. The standard error of the slope SE(b1) = 0.0827. Margin of error ME for a 99% Confidence Interval for the slope of the Population regression line is: 0.1161 0.2322 0.4644 0.3483

You extract approximately 5,000 observations from the Current Population Survey (CPS) and estimate the following regression function: AHE= 3.32 -0.45 x Age, R² =0.02, SER= 8.66 (1.00) (0.04) where AHE is average hourly earnings, and Age is the individual's age. Given the specification, your 95% confidence interval for the effect of changing age by 5 years is approximately: OA. [$2.32, $4.32]. B. [$1.86, $2.64]. C. [$1.35, $5.30]. D.

A regression of average weekly earnings (AWE, measured in dollars) on age(measured in years) using a random sample of college-educated full-timeworkers aged 25–65 yields the following: AWE = 696.7 + 9.6 X Age, R2 = 0.023, SER = 624.1.a. Explain what the coefficient values 696.7 and 9.6 mean.b. The standard error of the regression (SER) is 624.1. What are the unitsof measurement for the SER? (Dollars? Years? Or is SER unit-free?)c.

A variety of summary statistics were collected for a small sample (13) of bivariate data, where the dependent variable was y and an independent variable was x. Thex variable is the number of doctorates awarded in sociology in the United States, while the y variable is the total number of space launches per year. We call this a spurious regression where the results show a relationship but the relationship is silly or utter nonsense.

In a simple linear regression you are told that the estimate of the slope coefficient was 0.7 and that the "t-statistic" for testing whether the slope parameter was unity or not was-2.4. What is the estimated standard error for the estimated slope coefficient? (The answer should be correct to two decimal places.) Answer:
Suppose that a researcher, using wage per hour data on 250 randomly selected male workers and 280 female workers, estimates the following OLS regression wage - 12.68+2.79xMale (0.18) (0.84) R = 0.06, s-3.10 where Male is a dummy variable that takes the value 1 if the worker is male and 0 if female: s represents the standard error of the regression and in brackets homoskedastic std errors are reported. The researcher wants to find the gender pay gap as percentage bf the wagé per hour of women. According to this information the gender pay gap on average against women is approximately -22% -25% -38% O-16%
This regression is based on cross-section data of 1744 individuals and the relationship between their weekly earnings (in dollars) and age (in years) during 2020. The regression yielded the following result: Estimated(EARN) = 239.16 + 5.20(Age) , R = 0.05, SER = 287.21 Standard errors are reported as hereunder: SE(intercept) = (20.24) SE(Age) = (0.57) (a) Is the relationship between "Age" and "EARN" statistically significant? (b) Explain the meaning of heterskedasticity. Is there any reason to be concerned about heteroskedasticity in this model? Briefly explain your reasons. (c) Construct a 95% confidence interval for the slope coefficient, and use it to test for the statistical significance of the slope coefficient. (d) Construct a 95% confidence interval for the intercept coefficient, and use it to test for the statistical significance of the intercept coefficient.
