1. which of the following is the correct histogram for the

Explanation:

Step1: Count for [60,65)

There are no values in the dataset in the range [60,65), so the frequency is 0.

Step2: Count for [65,70)

The values 65, 67, 68, 69, 69 in the dataset are in the range [65,70). So the frequency is 5.

Step3: Count for [70,75)

The values 72, 73, 73, 74, 74, 74, 74, 74 in the dataset are in the range [70,75). So the frequency is 8.

Step4: Count for [75,80)

The values 75, 75, 75, 77, 78, 78, 79, 79 in the dataset are in the range [75,80). So the frequency is 8.

Step5: Count for [80,85)

The values 80, 81, 82, 82, 82, 82 in the dataset are in the range [80,85). So the frequency is 6.

Step6: Count for [85,90)

The values 85, 86, 88, 88 in the dataset are in the range [85,90). So the frequency is 4.

Answer:

Height	Frequency
[65,70)	5
[70,75)	8
[75,80)	8
[80,85)	6
[85,90)	4
