1. Nurse Sidney wanted to do a study on the relation of working overtime and perceived stress in the floor nurses at a local hospital. She asked, on average, how many hours a week each nurse worked overtime. She then asked what their level of stress is on a scale of 1 to 10. She constructed the table below to reflect the scores:

Participant	Number of OT hours (X)	Perceived stress (Y)
1	12	8
2	14	7
3	5	2
4	9	6
5	6	5
6	13	8
7	7	5
8	2	3
9	9	8
10	15	9

2. Below, construct a scatterplot of data.Hint- In word, you can easily add your own chart. Click on "insert" from the bar at the top of the document and click on "chart". From the box that pops up, click on "scatterplot". From there, you can enter the values from x and y. You can also draw a scatterplot and upload the photo?

3. Next, calculate the Correlation between the number of OT hours worked and perceived stress, as reported by the nurses. You can either use the formula found in this week's PowerPoint, or you can calculate it using an excel worksheet. The directions are found on this website: https://www.extendoffice.com/documents/excel/4152-excel-calculate-correlation-between-two-variables.html

What is the correlation coefficient between number of overtime hours worked and perceived stress? Show how you got that answer:

4. Explain the following:

• What is the strength of the correlation?
• What is the direction?
• Discuss how the number of OT hours relates to perceived stress, according to the data shown
