Final answer:
To express the difference in means as a multiple of the larger MAD, divide the difference by the larger MAD.
Step-by-step explanation:
To express the difference in means as a multiple of the larger MAD, we first need to determine which MAD is larger. The MAD for the fall data is 2.8 cookies, and the MAD for the spring data is 2.6 cookies. Since the MAD for fall is larger, we will use it as the denominator in our calculation.
The difference in means is 24 - 23 = 1 cookie.
To express this difference as a multiple of the larger MAD, we divide the difference by the larger MAD:
1 / 2.8 = 0.3571
Therefore, the difference in means is approximately 0.3571 times the larger MAD.
