Find the range, variance, mean and standard deviation mean 0.47‘ 1.25 tandavtev B. you are given this summary statistics (Q1-115,m 170, and Qu- 260), find the following i. Interquarile range QR) ii. endpoints of the inner fence in a box plot

Answer 1

Answer Date: 07/04/2019 a) The range of data is, Range= Maximum-Minimum = 1.55-1.37 -0.18 The range of data is 0.18 The mean of data is 1.53 +1.501.37 +1.51 +1.55 +1.421.41+1.48 1 .47 The mean of data is 1.47

b) The interquartile range (IQR) is, IQR = QU-QL =260-115 = 145 The interquartile range (IQR) is 145 The Lower Fence (LF) is, LF-QL-1.5(IQR) = 115-1.5(145) =-102.50 The Lower Fence (LF) is -102.50

The Upper Fence (UF) is, UF Q3+1.5(IQR) 2601.5(145) = 477.50 The Upper Fence (UF) is 477.50
