Question 13 of 20
1.0 Points
Accepted characters: numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).NOTE:For scientific notation, a period MUST be used as the decimal point marker.
Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values.
For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.

A statistics professor has just given a final examination in his statistical inference course. He is particularly interested in learning how his class of 40 students performed on this exam. The scores are shown below. 77 81 74 77 79 73 80 85 86 7383 84 81 73 75 91 76 77 95 7690 85 92 84 81 64 75 90 78 7882 78 86 86 82 70 76 78 72 93

Compute the standard deviation of these test scores. Place your answer, rounded to 2 decimal places in the blank. For example, 5.34 would be a legitimate entry.
