Answer:
I guess this is how to do it....
3×(1/3 of x + 8)=11.
use the 3 to multiply the numbers in the bracket.
3x+24=11.
3x=11-24.
3x=-13.
x= -13/3.
x= -4.33.
Answer: ( 1.25, 1.55)
Therefore at 95% confidence interval (a,b) = ( 1.25, 1.55)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 1.4
Standard deviation r = 0.5
Number of samples n = 42
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
1.4+/-1.96(0.5/√42)
1.4+/-1.96(0.0772)
1.4+/-0.1512
1.4+/-0.15
= ( 1.25, 1.55)
Therefore at 95% confidence interval (a,b) = ( 1.25, 1.55)
Answer:
The answer is 1400
Step-by-step explanation:
