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

Consider the following data: 12,10,13,3,4,6 Step 2 of 3 :
Calculate the value of the sample standard deviation. Round your
answer to one decimal place.

4,3,7,6,2,8
Step 1 of 3: Calculate the value of the sample variance. Round
your answer to one decimal place.
Step 2 of 3: Calculate the value of the sample standard
deviation. Round your answer to one decimal place.
Step 3 of 3: Calculate the value of the range.
Thank you :)
