Question

use the ogive to approximate (a) the number in the sample, (b) the location of the greatest increase in frequency. male beagles (a) the approximate number in the sample is . (b) choose the correct location of the greatest increase in frequency below. a. 27.5 - 28.5 pounds b. 20.5 - 21.5 pounds c. 23.5 - 24.5 pounds d. 33.5 - 34.5 pounds

Explanation:

Step1: Find total cumulative frequency

The last - point on the ogive gives the total number of data points in the sample. Looking at the ogive, the cumulative frequency at the end is 50. So the number in the sample is 50.

Step2: Identify location of greatest increase

The greatest increase in cumulative frequency occurs where the slope of the ogive is the steepest. By observing the ogive, the steepest part of the curve is in the interval corresponding to weights 23.5 - 24.5 pounds.

Answer:

(a) 50
(b) C. 23.5 - 24.5 pounds
