Determine the standard error of the estimated slope coefficient for the price of roses (point F) and whether that estimated slope coefficient is statistically significant at the 5 percent level.
A. 9.42 and statistically significant since the t-statistic is greater than 2 in absolute value.
B. 9.42 and statistically insignificant since the t-statistic is less than 2 in absolute value.
C. 4.74 and statistically insignificant since the P-value is greater than 5 percent.
D. 4.74 and statistically significant since the P-value is greater than 5 percent.
