(1) A recent poll by the Texas Tribune asked 996 Texas voters whether they would support Beto O'Rourke or Greg Abbott for governor. 552 of these voters said they supported Abbott and 444 said they supported O'Rourke (these numbers drop respondents who were undecided or planned to vote for another candidate, but we'll ignore that in our analyses below). (a) Based on this poll, what is your estimate of the proportion of Texas voters who support Abbott (b) Form a 95% confidence interval for this estimate. (c) Form a 99% confidence interval for this estimate. (d) Conduct a hypothesis test at the .05 significance level to assess whether Abbott really has a majority or whether the election could be tied. Be sure to formally specify your hypotheses, show the steps of your calculation and explain briefly what your result tells you about the can- didates' support in the population
