1. You believe that the price of Zoom Videoconferencing stock and the price of American Airlines stock will move in opposite directions. In order to test this relationship, we do a simple regression with the following variables: A - dependent variable : month end price of American Airlines stock Z - independent variable: month end price of Zoom Videoconferencing stock Data from April 2019 through December 2020 (21 observations) is available Based on the data, we compute the following: Var (Z) = 20927.702 Cov (A,Z) = -899.153 E(A) = 20.790 E(Z) = 187.530 Std Error of Estimate = 6.088 TSS = 1476.830
   1. Consider the equation A_t = b₀ + b₁ Z_t + _t Based on the numbers given above, complete the following table

Variable	Estimate	Std error	t-statistic
Slope b1		.00941
Constant b0		2.2088
R-square		N/A	N/A
F statistic		N/A	N/A

Are the coefficients (slope and/or constant) significant at the .05 level?
