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:
9/10
Step-by-step explanation:
step 1
Compare the slopes
therefore
An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
