Slope of a best-fit regression line
If data containing two variables X and Y (with X as the only predictor variable for Y) were standardized, the slope of a best-fit regression line would equal:
A) 1
B) a (intercept when y is regressed onto x)
C) Y
D) r (correlation between x and y)

A pile driver drives a post into the ground. The mass of the pile driver is 3,500 kg and it is dropped through a height of 8.0 m on each stroke. If the resisting force of the ground is 4.5 × 106 N, how far is the post driven in on each strok
B. Case II - Use t statistic, assuming variances are unknown but equal C. Case III -Use t statistic, assuming variances unknown and unequal D. Case IV - Use paired t test
A solid cylinder has a mass of 5kg, a diameter of 9cm and is 60cm high. it starts at point A and must be moving at 2m/s so it slides on to a convyer belt (moving at 2m/s) at point D.
The correlation (r) between these two variables is 0.67. The variances of x and y, respectively, are 14.57 and 8.16. The means of x and y are 20.00 and 9.31. What is the intercept of the regression line the researchers used?
An astronaut on the planet Vimrom IV finds that she can jump a maximum horizontal distance of 13.00 m if her initial speed is 3.90 m/s. What is the acceleration due to gravity on this planet?
Suppose you have variables X and Y, and you attempted to regress Y on X (i.e., predict Y from X). If you add 10 to the value of every Y data point, what will happen to the equation of the best fitting line through your points?
Steam at 75kPa and 13 percent quality is contained in a spring-loaded piston cylinder device, with an initial volume of 2 m^3. Steam is now heated until its volume is 5 m^3 ad its pressure is 300 kPa. Determine the heat transferred to and the work
