X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
The right anser is A: 0.1395 because you multiply the two possibilities.
