Accu-Rating has just released its webcast report for last month. The report details the aggregate tuning hours (ATHs) for the top 20 radio stations broadcast over the web. (The ATH for a station is the sum total of all hours that listeners tuned to the station.) The report displays the following histogram: 0.40.30.20.10.0Relative frequency0.150.200.150.400.10200400 60080010001200ATH (in thousands of hours) Based on the histogram, find the proportion of ATHs in the sample that are less than 800 thousand hours. Write your answer as a decimal, and do not round your answer.

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.
