Answer:
Wouldn’t you have to round 2.386 to the nearest 100th so it would be 2.39
Like me know if I’m wrong.
Step-by-step explanation:
Hi I don’t know if this is right but I got that k is equal to 4 I got that because if you do
4 times 3/4 you get 12/4 that is equal to 3.
Now you have k + 3=7 you move 3 to the other side and make it negative
K= 7-3
K=4

Answer:
Sample range appears to be a biased estimator since it consistently underestimated the population range.
Step-by-step explanation:
The calculation of sample range appear to be a biased or unbiased estimator of population range is shown below:-
Sample range (x) Frequency (f) fx
9 1 9
14 1 14
15 2 30
16 1 16
17 4 68
18 2 36
19 1 19
20 3 60
21 5 105
22 2 44
23 1 23
24 2 48
25 4 100
26 4 104
27 2 54
28 4 112
29 3 87
30 1 30
31 5 155
32 2 64
Total 50 1,178
Mean sample range = ∑ fx ÷ ∑ f
= 1,178 ÷ 50
= 23.56
Therefore the sample range is not equal to population range that is
23.56 ≠ 32
Thus, Sample range appears to be biased estimator.
So, the correct option is A.
Answer:
No
Step-by-step explanation:
A tangent line is a line entirely exterior to the circle except for the one point of intersection that lies on the circle. It does not (and cannot) go through any points inside the circle.
