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:
89°
Step-by-step explanation:
Ok so the measure of a triangle is 180°.
We have one angle, so we need to find m∠ACB.
A line is 180°.
180-150= 30.
m∠ACB=30°.
m∠BAC=61°.
180-(61+30)=89°
