The median is 86.
The mean, or average, of 75, 82, 93, and 86 is 84.
The set is bimodal: its modes are 84 and 86 which appear twice. All the other numbers appear at most once.
The composite numbers are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86 ,87, 88
The conversion formula is: F = (C x 1.8) + 32F = (28 x 1.8) + 32F = 50.4 + 32Fahrenheit = 82.4°

For 98 78 86 88 84 81 93 92 89 and 81: σ=6.2361
8 numbers, so the median is the mean average of the 4th and 5th numbers. 4th number is 86 5th number is 86 median = (86 + 86) ÷ 2 = 86.
