Question 1204221: According to research, the mean cost of safety equipment per year for colleges in Canada is $37,000.00. Suppose that these costs are normally distributed with a standard deviation of $5,000.00. If a Canadian College is selected at random, find the following probabilities.
For parts (b) express your answers as probabilities in decimal form (i.e. 0.0003 instead of 0.0300%), and round your answers to 4 decimal places.

(b) The cost is above $38,150.00.

For part (c), round your answer to 2 decimal places.
(c) What amount of cost is the cut-off for the top 10.20% of Canadian Colleges?
