PS296 Lecture Notes - Lecture 6: Standard Deviation
Example:
Avneet is a Raptors fan and loves all types of music, including music created by Drake. Drake is the
Global Ambassador for the Toronto Raptors and attends an average of 30 home games during the
regular season. Assuming his home game attendance is normally distributed with a standard deviation
of 3 games, what is the probability of Drake attending 25 games or less during the regular season?
x = 25
µ (mean) = 30
σ (standard dev) = 3
Z = 25-30 / 3 = -1.667
1.67 on table = 0.4525 (smaller portion = 0.0475)
x = 25 would be smaller portion of standard deviation curve
The probability of Drake attending 25 games or less during the regular season is .05. (don't put lead
0/before decimal in APA format)
Example:
Bronwynne aspires to be a police officer. An experienced Waterloo Regional Police constable earns an
average annual salary of $85,000. Assuming salaries are normally distributed with a standard deviation
of $5,000, what is the probability of an experienced Waterloo Regional Police constable earning
$92,000 or more?
x = 92,000
