Concept explainers
(a)
To Calculate: the probability that a randomly selected passenger on this flight weights more than 200 pounds.
(a)
Answer to Problem 10.53E
Do not have the exact shape of the population distribution
Explanation of Solution
Given:
Population is not
It cannot be calculated the probability for an individual, because do not have the exact shape of the population distribution. Since only now it is not normal, but also not non-Normal.
(b)
To Calculate: the probability that the mean weights of the passengers on the flight exceeds 200 pounds and explains.
(b)
Answer to Problem 10.53E
0.0594
Explanation of Solution
Given:
Formula used:
Calculation:
It can be calculated the population mean weight, because the central limit theorem said that the sampling distribution of the sample mean is about normal, when the sample is enough large. Moreover, the sample size of
The corresponding probability using the normal probability table
