A sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters. Give a point estimate for the population variance. Round your answer to three decimal places. 1.15,1.24,1.15,1.27,1.13

S² = 0.004

Step-by-step explanation:

Point estimate for the population variance is S²

S² = Sample Variance

∑ = Sum

= Term in data set

= Sample mean

n = Sample size

Sample mean ()  =

   =

   =

  = 1.188

    -                      

1.15  -   1.88  =       0.038        0.001444

1.24  -  1.88  =       0.052        0.002704

1.15  -  1.88   =       0.038        0.001444

1.27 -   1.88  =       0.082        0.006724

1.13  -   1.88  =       0.058        0.003364

5.94                      0.268          0.01568  

 =  0.0157

S² =   =  0.0039

S² = 0.004

i think it would be c
