Question

Weights​ (in grams) of randomly selected chocolate candies are represented in the table below. Find the range and standard deviation. 0.956 0.912 0.926 0.843 0.939 0.881 0.913 0.912 0.957 0.947 0.918 Find the range. rangeequals 0.113 g Find the standard deviation. sequals nothing g ​(Round to four decimal places as​ needed.)

Answer 1

From given data values, minimum value = 0.843 and

maximum value = 0.957

=> Range = maximum value - minimum value = 0.957 - 0.843 = 0.114

=> Range = 0.114

Using Excel we get, sample standard deviation = 0.0338

Note : population standard deviation = 0.0322
