Question 24 options: The data shows sugar consumption (pounds per year per person) in the United States for a sample of 5 years. Year Sugar Consumption 1900 46 1920 71 1940 77 1960 79 1980 86 2000 106 The mean of year is 1950 and the standard deviation of year is 37.4. The mean of sugar consumption is 77.5 and the standard deviation is 19.6 The correlation coefficient between Year and Sugar consumption is 0.95 [Useful formulas: slope=rSy/Sx and intercept = mean of Y – (slope * mean of X)] What is the R-square of this regression?

1. What is the correlation
between the selling price and square footage (three decimal
places)?
2. What is the intercept for the regression line predicting
selling price from square footage (no decimal places)?Selling_Price
= Intercept + Slope * Square_Footage
3. What is the slope for the regression line predicting selling
price from square footage (three decimal places)?Selling_Price =
Intercept + Slope * Square_Footage
4. What is the predicted selling price for a 2400 square foot
house (no decimal places)?Selling_Price =...
Is it reasonable to claim that the average number of observed tornadoes per year is different from the average number of tornado related deaths per year? 5. What test/procedure did you perform? a. One-sided t-test b. Two-sided t-test c. Regression d. Confidence interval 6. What is the P-Value/margin of error? a. 0.007034504 b. 0.34922 c. 4.07497E-24 d. 2.03749E-24 e. None of these 7. Statistical Interpretation a. Since P-value is very small we are confident that the number of tornadoes will...
