Answer: 32
Step-by-step explanation:
Sum of n observations = n x Mean of n observations
Given: The mean number for 10 stops = 6.3.
Sum of people getting off from these 10 stops = 10 x 6.3 = 63
After the tram stops at the 11th stop, the mean is 8.6.
Sum of people getting off from these 11 stops = 11 x 8.6 = 94.6 ≈ 95
Number of people got off the tram at the 11th stop = 95-63 = 32
