Answer:
Step-by-step explanation:
We have to find the derivative of the following function:
Now, differentiating both sides with respect to x we get,
⇒ (Answer)
{Since, we know that, and }
B is going to be where A is
If you put 5 which means its 2 1/2 ( I think) Because two 1/2 makes one.
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 * .
