According to Thompson Financial, last year the majority of companies reporting profits had beaten estimates. A sample of 162 companies showed that 94 beat estimates, 29 matched estimates, and 39 fell short. A. What is the point estimate of the proportion that fell short of estimates?
B. Determine the margin of error and provide a 95% confidence interval for the proportion that beat estimates. If required, round your answers to four decimal places.
C. How large a sample is needed if the desired margin or error is 0.04?

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 : )
