77

70

81

84

86

69

70

	69
	70
	73.5
	77

10.

	horizontal bar
	vertical bar
	Pareto
	pie

Answer 1

Question (16)

When two events can not occur at the same time, they are termed as mutually exclusive events. They can also be called disjoint events

So Answer is Option A

Question (17)

Given daily high temperature in Philadelphia over an eight-day period are

69

77

70

81

84

86

69

70

Arranging them in ascending order we have

69 69 70 70 77 81 84 86

There are 8 values here in asceding order, So Median will be average of 4th and 5th values

Median = (70 + 77)/2

= 147 / 2

= 73.5

So Answer is Option C

Question (18)

A pie chart is used to compare the relative sizes of the classes in a frequency distribution and together they comprise all possible categories.

So Answer is Option D
