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)
I got you !
Step-by-step explanation:
45 bulbs planted in first year.

Answer:
(-13,12)
Step-by-step explanation:
So, first, you make two separate equations.
4 + x = -9 (The 4 is from Q and the -9 is from V)
-11 + y = 1 (The -11 is from Q and the 1 is from V)
Then, you subtract 4 from both sides on the first one, and subtract -11 from both sides on the second one.
You should get:
x = -13
y = 12
