Answer:
To find the mean daily passenger count per plane, we need to calculate the average of the passenger counts for the sample.
We can do this by adding up all the passenger counts and dividing by the number of planes in the sample:
(123 + 132 + 158 + 77 + 158 + 123 + 132 + 123 + 158 + 77) / 10
= 1259 / 10
= 125.9
Therefore, the mean daily passenger count per plane is approximately 125.9 passengers.
