Missing Test Scores
A student went to a professor's office to make up a test. The professor
graded the exam and computed the mean and standard deviation of all of
the test scores. Unfortunately, he forgot to record the student's grade
and lost the test. Find the missing test score if the standard deviation
was 8.596. The other test scores were:
65,71,72,72,74,74,75,75,75,75,75,78,78,79,79,81,81,81,81,82,83,89, 90,90,92,94,96,98,100
