Answer:
A
Step-by-step explanation:
Given
f(x) = 
let f(x) = y and rearrange making x the subject
y = ( multiply both sides by 4 )
4y = x + 3 ( subtract 3 from both sides )
4y - 3 = x
Change y back into terms of x
(x) = 4x - 3 → A

the correct answer is 0.35
Step-by-step explanation:
Answer:
Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.
Step-by-step explanation:
In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.
<em>Statistically</em>, this means that the person can be 97% sure (not 100%) that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.
Small sample size may also lead wrong estimates.
