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 38.7% bullish, 22.6% neutral, and 38.7% 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

All that I know is that since it is parallel the slopes have to be the same. So it would have to be y=2x+b. And in this I think b would be 4. So the final answer I think should be y=2x+4.

I hope I helped!!
