Answer:
And using a calculator, excel or the normal standard table we have that:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
They select a sample size of n=9 people.The distribution for the sample mean is given by:
And we want to find this probability:
In order to the helicopter can safely lift off. We can use the z score formula given by:
And using a calculator, excel or the normal standard table we have that:
Answer:
The third time = 11.64 seconds
Step-by-step explanation:
Let the average time be x
The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:
Average = (10.84 + 13.52 + x) ÷ 3 = 12.0
