(b) Over the long term, the proportion of bearish members is 0.30. Conduct a hypothesis test at the 1% level of significance to see if the current sample results show that bearish sentiment is above its long term average of 0.30.

All investors must be a member of this professional association. Therefore, it is dangerous to generalize these results to all investors. One particular professional association of 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. The survey results showed 37.7%bullish, 23.4% neutral, and 38.9% bearish. Assume these results are based on a sample of 300 members.(a) Over the long term, the proportion of bullish members is 0.39.
