Answer:
And the best option would be:
D. (0.191 to 0.249)
Step-by-step explanation:
For this case we know that the mean is:
And the standard error is given by:
We want to construct a 68% confidence interval so then the significance level would be :
and . The confidence interval is given by:
Now we can find the critical value using the normal standard distribution and we got looking for a quantile who accumulate 0.16 of the area on each tail and we got:
And replacing we got:
And the best option would be:
D. (0.191 to 0.249)
Answer:
11/12
Step-by-step explanation:
(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12
__
You can also work this using improper fractions:
(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)
= (11×5)/(6×2×5) = 11/(6×2) = 11/12
Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
