**Question:**What is the first quartile of the following data set?18, 20, 21, 23, 24, 26, 29, 30, 34, 37, 40**Options:**- A. 18- B. 20- C. 23- D. 21The correct answer is D. 21.**Explanation:**The first quartile (Q1) is the median of the lower half of the dataset. To find Q1:1. The data set is: 18, 20, 21, 23, 24, 26, 29, 30, 34, 37, 40.2. Split the data into two halves: Lower half = 18, 20, 21, 23, 24.3. Find the median of the lower half: 21.Therefore, the first quartile is 21.

3. An article by S. M. Berry titled “Drive for Show and Putt for Dough (Chance, Vol 12(4), pg 50-54)” discussed driving distances of PGA players. The mean distance for tee shots on the 1999 men’s PGA tour is 272.2 yards with a standard deviation of 8.12 yards. Assuming that the 1999 tee-shot distances are normally distributed, find the percentage of such tee shots that went a. between 260 and 280 yards. b. more than 300 yards. 4.

6) Suppose you had the following body temperature readings, all in °F: (Don't forget to answer the questions in parts (d) and (e)). 96.21 97.65 97.39 97.97 97.28 99.43 a) calculate the mean, variance and standard deviation. b) now convert these readings to °C (us biologists like the metric system, after all). To convert, remember that °C = °F/1.8 - 32/1.8. For example, to convert the first reading you would do: 96.21/1.8 - 32/1.8 = 53.43 - 17.78 = 35.67. c) now calculate the mean, variance and standard deviation of the converted data. d) take the mean you calculated in (a) and convert this to Celsius using the same formula you used in (b). Are you surprised by the results? Why or why not? e) take the standard deviation from (a) and divide it by 1.8. Can you explain the results? Why didn't you have to subtract 32/1.8? Watch your math in this step!
