Homework Statement
I'm doing a past paper for my statistics course, and there's no provided solutions. I want to know if my attempt is correct. This is part of the paper:
Homework Equations
N/A
The Attempt at a Solution
i) Q0 = 1.06, Q1 = 1.335, Q2 = 2.04, Q3 = 2.275, Q4 = 2.64
ii) IQR = Q3 - Q1 = 0.94
IQR x 1.5 = 1.41
Outliers outside: [Q1 - 1.41, Q3 + 1.41] = [-0.075, 3.685]
Therefore no outliers.
iii) Skewed to the left
iv) 1.8810 ± 1.906 [(0.5239)/sqrt(20)]
= [1.6577, 2.1043]
v) Assumed it is a normal distribution.Apart from the missing boxplot, are these correct?
