Final answer:
The mean paycheck for the sample of high school students is $211.07.
Step-by-step explanation:
The stemplot shows the distribution of monthly paychecks for a sample of high school students. The stemplot titled 'Student Monthly Paychecks' has the following values:
67, 85, 92, 123, 147, 181, 181, 196, 198, 213, 252, 277, 287, 325, 459
To find the mean paycheck:
- Add up all the values: 67 + 85 + 92 + 123 + 147 + 181 + 181 + 196 + 198 + 213 + 252 + 277 + 287 + 325 + 459 = 3166
- Divide the sum by the number of values: 3166 / 15 = 211.07 (rounded to two decimal places)
Therefore, the mean paycheck is $211.07. This mean indicates the average amount of money earned per month by the high school students in the sample.
