Step-by-step explanation:
Answer:
As per the statement:
Let Event A represents the probability that a vehicle is white and Event B represents the probability that it is a pick up truck .
then;
and 
It is also given that:
The Probability that it is a white pick up truck is 0.06.
⇒
where 
represents that it is white pick up truck.
We have to find the the probability that the vehicle is white {given that the vehicle is a pickup truck}
We use the formula:
where
represents that the pick up truck vehicle is white.
Substitute the given values we get;
Therefore, the probability that the vehicle is white, given that the vehicle is a pickup truck is 0.4
A. The mean and standard deviation.
The mean of a sampling distribution is approximately equal to the mean of the population. Given that the mean of the population is equal to 174.5, the mean of the sampling distribution is also this value.
The standard deviation of a sample distribution is equal to,
u(m) = u/sqrt n
Substituting the known values,
u(m) = 6.9 / sqrt 25 = 1.38
b. Get the z-score of both items,
z-score = (data point - mean) / standard deviation
z-score of 172.5
z-score = (172.5 - 174.5) / 1.38 = -1.49
This translates to 0.068.
z-score of 175.8
z-score = (175.8 - 174.5) / 1.38 = 0.94
This translates to 0.83.
The difference between the two z-scores is 0.762.
The number of samples with this height is 0.762(200) which is equal to approximately 152.
c. z-score of 172 centimeters
z-score = (172 - 174.5) / 1.38
z-score = -1.81
This translates to 0.03.
The number of people with this height from the sample is (0.03)(200) = 6
