Mean number of flights are 54 with a standard deviation of 13 What is the probability that the farmer will count 60 or fewer flights on average in the next 40 rows down? Round to four places

Solutions

Expert Solution

Solution :

Given that,

mean = = 54

standard deviation = = 13

n = 40

= 54

= / n = 13/ 40=2.055

P( < 40) = P[( - ) / < (60-54) / 2.055]

= P(z < 2.92)

Using z table

=0.9982

probability= 0.9982

Bird’s data analyst wants to model the sample mean distance of scooter rides. They plan to take a random sample of 41 scooter rides and to record the distance traveled on each ride (distance before the rider “releases” the scooter and the charge is processed). They decide it is reasonable to assume that the distribution of distances is approximately normal, but they don’t know the variance of the distribution. In the sample, the mean is 0.54 mile and the standard...
