You regress the excess returns of Apple (AAPL) on the excess returns of the S&P500. A portion of the regression output is below. Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 0.0307 0.0116 0.0075 0.0540 X Variable 1 1.3771 0.2271 0.9225 1.8317 Question 10 2 pts What is the t-stat for the estimate of alpha, under the null hypothesis that alpha=0? 2.17 6.04 1.66 2.65 0.38 Question 11 2 pts What do the results of the estimated alpha of AAPL imply with regards to the existence of abnormal returns there are abnormal returns since we can reject that alpha = 0 there are abnormal returns since we cannot reject that alpha = 0 there are NO abnormal returns since we can reject that alpha = 0 there are NO abnormal returns since we cannot reject that alpha = 0

A grinding wheel is said to be of C•hard grade if it holds the abrasive grains more securely. Incorrect options: A•soft grade - This option is incorrect because a soft grade grinding wheel would not hold the abrasive grains securely. B•medium grade - This option is incorrect because a medium grade grinding wheel may not hold the abrasive grains as securely as a hard grade wheel. Summary: The correct option is C•hard grade because a hard grade grinding wheel is able to hold the abrasive grains more securely than soft or medium grade wheels.

1. Draw the gel electrophoresis results for the following 16 kb plasmid when the plasmid is cut with restriction enzyme A, with restriction enzyme B and with both A and B restriction enzymes. The A enzyme cuts at positions 0 and 9.2 kb and the sites are shown as white. (0 is at the top of the circle.) The B enzyme cuts at positions 3.8, 7 and 13.2 kb and the sites are shown as gray. Show the electrical polarity of the gel, the bands, and their sizes in your drawing. Make sizes consistent between gel lanes. Explain why the concept of charge density is important for gel electrophoresis.
