1?. [2 pt] Which of the following statement is correct? (a) The estimated slope for the attendance is only $5832. This means that, when keeping everything else the same, the revenue does not depend much on the attendance. (b) The tstatistic associated with the slope for the attendance variable is 11.65. This means that there is too much noise to determine if the slope is denitely positive. (c) The p-value for the concession variable is 0.325. This means that the number of concession stands is not a statistically signicant variable to determine the revenue. (d) The p-value for the concession variable is 0.825. This means that the mrmher of concession stands is a statistically signicant variable to determine the revenue
