Answer:
We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.
Step-by-step explanation:
Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.
In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.
Confidence Interval can be calculated using M±ME where
- M is the sample mean difference between Store A and Store B purchase amounts
- ME is the margin of error from the mean
For this case we have the following functions:
We have to:
is given by:
Thus, the correct option is the option is A.
On the other hand,
Thus, the correct option is the option is A.
We also have:
Thus, the correct option is the option is B.
Last we have:
Thus, the correct option is the option is C.
ANswer:
Option A, A, B, C
