Question

use the ogive to answer parts a) through d). male beagles a) what is the cumulative frequency for a weight of 27.5 pounds? (type an integer or a decimal.) b) what is the weight for which the cumulative frequency is 45? (type an integer or a decimal.) c) how many beagles weigh between 22.5 and 29.5 pounds? (type an integer or a decimal.) d) how many beagles weigh more than 30.5 pounds? (type an integer or a decimal.)

Explanation:

Step1: Find cumulative - frequency for 27.5 pounds

Locate 27.5 pounds on the weight axis. Then, read the corresponding cumulative - frequency value on the cumulative - frequency axis.

Step2: Find weight for cumulative - frequency of 45

Locate 45 on the cumulative - frequency axis. Then, read the corresponding weight value on the weight axis.

Step3: Find number of beagles between 22.5 and 29.5 pounds

Find the cumulative - frequency at 29.5 pounds and 22.5 pounds. Subtract the cumulative - frequency at 22.5 pounds from the cumulative - frequency at 29.5 pounds.

Step4: Find number of beagles weighing more than 30.5 pounds

The total number of beagles is the cumulative - frequency at the highest weight value (assume it's 50). Subtract the cumulative - frequency at 30.5 pounds from the total number of beagles.

Answer:

a) [Read the cumulative - frequency value at 27.5 pounds from the ogive]
b) [Read the weight value at cumulative - frequency = 45 from the ogive]
c) [Cumulative - frequency at 29.5 pounds - Cumulative - frequency at 22.5 pounds]
d) [Total number of beagles - Cumulative - frequency at 30.5 pounds]
