What is the IQR of the data? 24) We know that one way to detect outliers in a data set is to produce a boxplot. Answer the following questions that deal with boxplots a. Does the absence of an asterisk() in a boxplot Indicate that the data is normally distribut Why or why not? b. Which of the following boxplots below is most obviouslv skewed left? Decide upon the co 0 ???Explanation / Answer
(a) How many colleges were sampled: 40
(b) What was the average tution: 23.675
(c) 25% of those surveyed have a tution fee larger than ehat amout: Q3 = Third Quartile = 26.000
(d) What IQR of this data: Q3 - Q1 = 26.000 - 21.000 = 5.000
24.
The absence of an asterisk (*) in a boxplot does not indicate that the data is normally distributed. REASON: The absence of an asterisk (*) only indicates that there are no outliers in the data. It does not conclude on Normal Distribution at all.
25. Find the measures of dispersin:
(i) Range = Maximum - Minimum = 32.000 - 15.000 = 17.000
(ii) Standard deviation = 3.866
(iii) Variance = 3.8662 = 14.9460
