The study was sponsored by the New York Times, and the stores (in order) are D’Agostino, Eli’s Manhattan, Fairway, Food Emporium, Gourmet Garage, Grace’s Marketplace, and Whole Foods.
Given data
0.56 , 0.75 , 0.10 , 0.95 , 1.25 , 0.54 , 0.88
Now we have to find the range, variance, and standard deviation for the given sample data.
Range :
The range is a simple measure of variation in a set of random variables. It is difference between the biggest and smallest random variable.
Range = Maximum value - Minimum value
Given data
0.56 , 0.75 , 0.10 , 0.95 , 1.25 , 0.54 , 0.88
Therefore, the range of the seven random variables 0.56 , 0.75 , 0.10 , 0.95 , 1.25 , 0.54 , 0.88
