An investment broker reports that yearly returns on common stocks are normally distributed with a mean of 12.41 percent and a standard deviation of 20.64 percent. (round all k amounts to 4 decimal places. negative amounts should be indicated by a minus sign. for z, use the inverse normal function and round to 4 decimal places, except when the percentile for part a is just 5, then you must interpolate.) (a) what percentage of yearly returns are at or below the 10th percentile of the distribution of yearly

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: the answer is ann
