Ans:
1)According to range rule of thumb,Range is four times the standard deviation.
standard deviation=range/4
True
2)Positively skewed means right skewed.
false
3)third quartile is always greater than first quartile
True
4)Numerical data set can have one or two or multiple modes(unimodal data or bimodal data)
False
5)IQR=Q3-Q1 and represents the middle 50% of the data.
True
6)True
lower fence=Q1-1.5*IQR
upper fence=Q3+1.5*IQR
if any point is outside these limits,then it is an outlier.
7)False,for positively skewed data,mean is greater than the median.
8)data collected from all of the population is associated with parameter.
Option C is correct.
9)Number of suitcases in a plane is discrete data
10)Hair color is categorical/nominal data.
11)Nominal
