Answer:
c. [70.30, 74.70]
Step-by-step explanation:
Confidence interval is a range of values in which there is a specified probability that the value of a parameter lies within that range.
The confidence interval of a statistical data can be written as.
x+/-zr/√n .......1
Given;
Mean gain x = 72.5 cm
Standard deviation r = 4.5 cm
Number of samples n = 16
Confidence interval = 95%
z (at 95% confidence) = 1.96 (from the table)
Substituting the values we have into equation 1;
72.5 +/- 1.96×4.5/√16
72.5 +/- 2.20 cm
[70.30, 74.70]
Therefore, the 95% confidence interval is
[70.30, 74.70] cm

-(9x+12)=-8x-(x+3)
-9x-12= -8x-x-3
-9x+9x=9
-9
if u look at the eq for x it has no value. but if u r asking a solution for a eq then it is -9
Answer:
q=<u>bp</u>
<u> </u><u> </u><u> </u><u> </u>a- cp
Step-by-step explanation:
<u>a</u> - <u>b</u><u> </u>= c
p q
Multiply through by pq
qa - bp = cpq
qa - cpq = bp
q [a-cq] = bp
q= <u>bp</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>a-cp
