Answer:
x=9
Step-by-step explanation:
First, distribute the 2 and each value in the parentheses.
2*x+2*5. This is the first half of the equation.
2*x+2*5= 3x+1 You can then simplify
2x+10=3x+1 Subtract 3x from both sides
(2x-3x)+10=(3x-3x[cancels out])+1
-x+10=1 Now subtract 10 from both sides
-x(10-10[cancels out to 0])=(1-10)
-x=-9 Since x is negative we need to solve for positive
x=9
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
