Explanation / Answer

a-1]

a-2]

Relative Frequency Histogram is B

b]

c-1]

Proportion the observations are at least 30 but less than 40 = 0.343

Percentage = 34.3%

c-2]

Proportion the observations are less than 40 = 0.821

Percentage = 82.1%

Class Frequency Relative Freq 10 to 20 30 0.214 20 to 30 37 0.264 30 to 40 48 0.343 40 to 50 25 0.179 Total 140 1.000
