d-2. What are the limits for outliers? (Round your answers to the nearest whole number. Negative amounts should be indicated by a minus sign.)

Answer 1

Please refer below provided Minitab output:

To get the output

Open Minitab - Go to Stat - Basic Satistics - Display Descriptive Statistics - In Satistics option choose the terms you want to calculate.

a) Mean = 340.4, Median = 293.5, Standard Deviation = 289.3

b) Coefficient of Skewness = 1.05

c) Since, Mean > Median, the shape of distribution is positively skewed.

d) The First and Third quartiles will be:

Q1 = 97.3 and Q3 = 510.8

e) There are five outliers.

f) The limits of outliers can be calculated as below:
