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 38.1% bullish, 22.8% neutral, and 39.1% 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. 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 0.39. What are your findings? Formulate the hypotheses that can be used to determine whether the bullish sentiment differs from its long term average of 0.39 H₂: p<0.39 HP 20.39 Hop≤0.39 H₂ p>0.39 Hp20.39 HP<0.39 M₁ -0.39 H₂P 0.39 M2039 HP≤0.39 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value (Round your answer to four decimal places) p-value= What is your conclusion Do not reject H There is insufficient evidence to conclude that the bullish sentiment differs from its long term average of 0.39 Reject H There is insufficient evidence to conclude that the bullish sentiment differs from its long term average of 0.39 Do not reject H There is sufficient evidence to conclude that the bullish sentiment differs from its long term average of 0.39 Reject H There is sufficient evidence to conclude that the bullish sentiment differs from its long term average of 0.39
(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 its long term average of 0.30. What are your findings? Formulate the hypotheses that can be used to determine whether the current bearish sentiment is above its long term average of 0.30.
