Transcribed Image Text:(a) Define the independent variable Period, where Period = 1 corresponds to the data for November 3, Period = 2 corresponds
to the data for November 4, Period = 3 corresponds to the data for November 7, and so on. Develop the estimated
regression equation that can be used to predict the closing price (in dollars per share) given the value of Period. Use x for
Period. (Round your numerical values to two decimal places.)
ŷ = 82.89 +0.38x
(b) At the 0.05 level of significance, test for any positive autocorrelation in the data.
State the null and alternative hypotheses.
