Answer:
B: The mean wingspan is 59 inches.
Step-by-step explanation:
The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.
B. the mean is 59 inches
if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.
