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 *
.
Answer:
(x, y)
(-1,0)
since the rest of the points aren't in the multiple choice well it's (-1,0)
You're probably supposed to find the value of p and not x, which is impossible to do.
Expanding gives

We're told that

which we can use to solve for p:



Answer:
Step-by-step explanation:
basic facts:
34% is the same as 34/100
the word 'of' in maths also means multiply
34% of 600 is the same as 34/100 * 600, which is 204
a quarter of 204 is the same as 1/4*204, which is 51
hopefully this helps!!
Answer:
26 inches
Step-by-step explanation:
5*5=25
25+1=26
