Height of eruption (in.) 127 96 110 150 140 110 100 130 110 126 135 116 118 129 128 120 135 130 102 141 Answer KSource 9 Styles Format

please help I'm being stopped by moving on with these three. PLEASE HELP. THANK YOU SO MUCH.

Answer 1

Solution:-

1) 5th class frequency : 138 - 149

Table Count Class 90-101 102-113 114-125 138-149

2) option 4. -By starting the horizontal axis at​ 100, the graph cuts off portions of the bars.

3) the 20th percentile is 29.

their average is the percentile = (24+34)/2 = 29

Your input: find the 20th percentile of 24,45,52,78,90, 120,34,67, 111,10. The pth percentile is a value such that at least p percent of the observations is less than or equal to this value and at least (100 - p) percent of the observations is greater than or equal to this value. The first step is to sort the values. The sorted values are 10, 24, 34,45,52,67,78,90, 111, 120. Since there are 10 values, then n 10. 20D _ .n__ 100 Now, calculate the indexi- 102 100 Since the index i is an integer, the 20th percentile is the average of the values at the positions i and The value at the positioi2 is 24 and at the positioni+1-3 is 34.
