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 *
1.15 1.15 - 1.188 = -0.038 1.444 *
1.15 1.15 - 1.188 = -0.038 1.444 *
1.24 1.24 - 1.188 = 0.052 2.704 *
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 * .
For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.
So:
We look for the factors of 18 and 36:
18: 1,2,3,6,9,18
36: 1, 2,3,4, 6,9,18 ...
Thus, the GFC of both numbers is 18.
Then, the GFC of and
is:
