The American Association of Individual Investors conducts a weekly survey of its members to measure the percent who are bullish, bearish, and neutral on the stock market for the next six months. For the week ending November 7, 2012 the survey results showed 38.5% bullish, 21.6% neutral, and 39.9% bearish (AAII website, November 12, 2012). Assume these results are based on a sample of 300 AAII members. a. Over the long-term, the proportion of bullish AAII members is .39. Conduct a hypothesis test at the 5% level of significance to see if the current sample results show that bullish sentiment differs from its long-term average of .39.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90Β° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, β6) is rotated 90Β° counterclockwise. (x, y) β (βy, x) 1. switch the x- and y-coordinates: (6, β3) 2. multiply the new x-coordinate by β1: (6(β1), β3) 3. simplify: (β6, β3) .
