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:
Tyrel scored 30 and Diego scored 15
Step-by-step explanation:
This is because the ratio of the score is 2:1 (Tyrel : Diego)
and if you add that together you get 3
which means you have to divide 45 by 3 which gives you 15
and this means I part = 15
so with the ratio 2:1 you have to multiply 15 by each ratio
so 15 x 2 = 30 and 15 x 1 = 15
which gives you 30 and 15
