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
Answer:
2 dollars
Step-by-step explanation:
if 8 limes costs 2 dollars, then 4 limes cost 1 dollar
you purchased 12 limes so since you already know what 8 limes coms, you could subtract that
12-8=4
now you need to find out how much for 4 limes which would be half the price of 8 limes.. which should be 1 dollar
so $2.00+$1.00= $3.00
finally 5 dollars minus 3 would result in a change of 2 dollars
