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
1. She earns 300 dollars an hour

Pie Chart
Step-by-step explanation:
The variable mentioned in this case is categorical. That is, it has no numerical value, and can only be put into categories.
Some of the basic rule In statistics to represent data using charts are as follows:
• For categorical variables (nominal/ordinal) variables, use pie charts and bar charts
• For interval/ratio variables, use histograms
A pie chart is a circular chart divided into wedge-like portions and is basically used to display percentage or proportion of categories in the data The percentage represented by each category is shown by the corresponding slice/portion of the whole pie.
