Round to three decimal places as needed.) Round to three decimal places as needed.) Round to three decimal places as needed.) (b) IQR Round to three decimal places as needed.) (c) The lower fence is Round to three decimal places as needed) nt tr . The upper fence is Round to three decimal places as needed.) Are there any outliers in the given data set? Click to select your answer(s)

Explanation / Answer

a)Q1 = 1.91
Q2 = 3.735
Q3 = 4.97

b)IQR = Q3 -Q1 = 3.06
c)
Lower inner fence: Q1 – (1.5 * IQR) = 1.91 - 1.5 * 3.06 = -2.68
Upper fence = Q3 + (1.5 * IQR) = 4.97 + 1.5 * 3.06 = 9.56

option B) no, all the values are between lower and upper
B) there are no outliers
