Answer:
A. We can select a lower confidence level and increase the sample size.
Step-by-step explanation:
The length of a confidence interval is:
Direct proportional to the confidence interval. This means that the higher the confidence level, the higher the length of the interval is.
Inverse proportional to the size of the sample.This means that the higher the size of the sample, the lower, or narrower, the length of the interval is.
Which of the following could we do to produce higher precision in our estimates of the population proportion?
We want a narrower interval. So the correct answer is:
A. We can select a lower confidence level and increase the sample size.
Answer: There are 120 different ways we can arrange reindeer.
Step-by-step explanation:
Since we have given that
Number of reindeer = 5
Number of them fly their sleigh = 4
We need to find the number of different ways we can arrange their reindeer .
For this we will use "Permutation":
here, n = 5
r = 4
So, it becomes,

Hence, there are 120 different ways we can arrange reindeer.

Step-by-step explanation:
The answer for finding the slope is -1/2
Answer:
a) e
b) c
c) a
Step-by-step explanation: Look at the number line. 0 shows that it has no probability while C is at 1/2 showing that it could be half-half. Then you can see one under E which means it is bound to happen.
