Given Data:
122 134 126 120 128 130 120 118
125 122 126 136 118 122 124 119
No of values = 16
percentile rank of 126 is
Formula for percentile rank of 126 = [(below no of values 126)x(0.5*no of 126)]/No of total values
Below No of 126 = 122 120 120 118 125 122 118 122 124 119 = 10
No of 126 = 2
percentile rank of 126 = [(10 x 0.5 x 2)/16] x100%
= [10/16] x 100%
0.625 x100%
percentile rank of 126 = 62.5% ~63%
The value 62.5 or 63 is not in options
so answer is Option "e" None of these

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
