1. Students in a small statistics class were asked which was their dominant hand and if they were in a STEM (science, technology, engineering, and math) major. Their results are listed below. Round to 4 decimal places.

	Right	Left	Total
STEM, Yes	6	1	7
STEM, No	7	2	9
Total	13	3	16

a.) What is the proportion of students in the class that are right-handed?

b.) What is the proportion of left-handed students in the class that are in STEM?

2. One of the symptoms of the flu is an elevated pulse rate. Pulse rates (in beats per minute) for n = 23 patients with the flu are provided. Use Minitab to answer the following

*Hint: adjust the output from Minitab to display the mean, the standard deviation, the minimum, Q1, median, Q3, maximum, and IQR and that will help answer all the questions below.

75	80	81	82	82	83	84	85	86	88	88	90
90	90	91	92	93	93	95	97	99	101	110

a.) Give the sample mean pulse rate. Use two decimal places in your answer.

b.) Find the standard deviation of the pulse rates. Use two decimal places in your answer.

c.) Give the five-number summary of these pulse rates.

d.) Are there any outliers? If so, which data points? Clearly show your work to justify your answer.
