Answer:i honestly dont know just trying to get points
Step-by-step explanation:
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 * .

The answer is zero. Oliver only has one. So one few would be zero
Answer: D is correct, 52.9%
Step-by-step explanation:
% decrease from 340 to 160, Where 340 is the old number and 160 is the new number
Percent change = (New number - Old number) / Old number x 100%
Percent change
= (160 - 340) / 340 x 100
= (-180) / 340x 100 = -52.94%
I hope this is clear, please mark as brainliest answer.
