5/2
Answer:
Point estimate for the population variance = 3.92 *
.
Step-by-step explanation:
We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;
X X -
1.13 1.13 - 1.188 = -0.058 3.364 * ![10^{-3}](https://tex.z-dn.net/?f=10%5E%7B-3%7D)
1.15 1.15 - 1.188 = -0.038 1.444 *
1.15 1.15 - 1.188 = -0.038 1.444 * ![10^{-3}](https://tex.z-dn.net/?f=10%5E%7B-3%7D)
1.24 1.24 - 1.188 = 0.052 2.704 * ![10^{-3}](https://tex.z-dn.net/?f=10%5E%7B-3%7D)
1.27 1.27 - 1.188 = 0.082 <u> 6.724 * </u>
<u> </u>
<u>= 0.01568 </u>
Firstly, Mean of above data,
=
=
= 1.188
Point estimate of Population Variance = Sample variance
=
=
= 3.92 *
.
Therefore, point estimate for the population variance = 3.92 *
.
