Answer C
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:
23
Step-by-step explanation:
sin theta = opp /hyp
sin H = 5/13
Take the inverse sin of each side
sin ^-1 (sin H) = sin ^-1 (5/13)
H =22.62 degrees
To the nearest degree
H = 23 degrees
