Question

The data below represents the three year rate of return (in percent) for a simple random sample of 40 small capitalization growth mutual funds.

27.4, 16.7, 10.8, 24.1, 35.9, 12.7, 28.5, 22.2, 18.4, 17.4, 22.6, 29.6, 11.6, 45.9, 16.6, 32.1, 47.7, 10.9, 18.4, 23.3, 18.2, 32.0, 25.5, 23.7, 38.1, 23.7, 14.7, 12.8, 31.1, 21.9, 18.4, 21.3, 27.0, 19.6, 15.8, 14.7, 37.0, 19.2, 18.5, 29.1

Use 10 as the first lower class limit and we want 8 classes. Since data values contain 1 decimal digit, your upper class limits must contain 1 decimal digit. (example 45.6)

5. What is the median of the data?
