The towing capacities (in pounds) of 25 four-wheel drive pickup trucks have a bell- shaped distribution, with a mean of 11830 pounds and a standard deviation of 2370
pounds. Use z-scores to determine if the towing capacities of the following randomly
selected four-wheel drive pickup trucks are unusual.
16500 pounds
18000 pounds
5500 pounds
11300 pounds

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
