ch 1 the following histogram represents the distribution of acceptance rates (percent accepted) among 25 business schools in 2004. in each class interval, the left endpoint but not the right is included, so the class intervals are 10 ≤ rate < 15, 15 ≤ rate < 20, etc. the number of schools with acceptance rates over 30% is: 12 10 5 13

Answer

Explanation:

Step1: Identify relevant intervals

Intervals for acceptance - rates over 30% are (30\leq\text{rate}<35) and (35\leq\text{rate}<40) and (40\leq\text{rate}<45) (assuming the histogram continues in a similar fashion).

Step2: Read frequencies from histogram

The frequency for the interval (30\leq\text{rate}<35) is 5, for (35\leq\text{rate}<40) is 5, and for (40\leq\text{rate}<45) is 3.

Step3: Calculate total

Add the frequencies: (5 + 5+3=13).
