The option that is not a correct description of the distribution of the amount spent by the 50 shoppers at the grocery store is D) The distribution is uniform, with all values equally likely.

<h3>What is a stemplot?</h3>

A stemplot is a graphical way of displaying numerical data that uses place value to group the data. The leftmost digits of the data values form the stem, and the rightmost digits form the leaf.

The distribution is symmetric, because the left and right halves of the stemplot are roughly mirror images of each other. The mean and median are both about $25, because the middle value of the data is $25, and the sum of the data values divided by the number of data values is also $25. The distribution is not skewed to the right or left, because there are no long tails or outliers on either side of the peak.

explain why the percentage of people with $300,000 or more increases so substantially across the age groups.
MrRa [10]

The percentage of people with $300,000 or more increases so substantially across the age groups because older individuals have an edge when it comes to accumulating wealth.

<h3>What are the age groups?</h3>

Simply put, older folks have more money because:

1. They have worked for longer periods of time and are thus anticipated to earn higher incomes and hold higher positions.

2. They have had more time to save and invest their money.

Every age group has a greater ability to save money during their working years. Young individuals just starting out in their jobs are less likely to amass enough money to be worth that much.

More about the age group link is given below.
