Answer:
The probability that the plane is oveloaded is P=0.9983.
The pilot should take out the baggage and send it in another plain or have less passengers in the plain to not overload.
Step-by-step explanation:
The aircraft will be overloaded if the mean weight of the passengers is greater than 163 lb.
If the plane is full, we have 41 men in the plane. This is our sample size.
The weights of men are normally distributed with a mean of 180.5 lb and a standard deviation of 38.2.
So the mean of the sample is 180.5 lb (equal to the population mean).
The standard deviation is:

Then, we can calculate the z value for x=163 lb.

The probability that the mean weight of the men in the airplane is below 163 lb is P=0.0017

Then the probability that the plane is oveloaded is P=0.9983:

The pilot should take out the baggage or have less passengers in the plain to not overload.
You need to find the percent of the 125 surveyed students to find the number of estimated students that like pizza.
58/125 = .464 or 46.4%
1500*.464 = 696 students like pizza.
Hope this helps!
