Question

Consider the following data: −2,−2,10,−2,10,10 Copy Data Calculate the value of the sample variance, standard deviation, and value of range. Round your answer to one decimal place .

Answer 1

solution:-

given values -2,-2,10,-2,10,10

=> sample variance = 43.2

explanation:-

=> standard deviation = 6.6 (rounded to one deciamal place)

explanation:-

standard deviation = sqrt(variance) = sqrt(43.2) = 6.6

=> range = 12

explanation:-

range = highest value - lowest value

range = 10 - (-2)

range = 12
