The number of assists per match for the setter on your school's volleyball team has a mean of 58 and a standard deviation of 7. If in the last game he made 77 assists, how many standard deviations is that from the mean?
To get the number of standard deviation that 77 is from the mean, we get the z-score: z-score is given by z=(x-μ)/σ where: μ-mean σ-standard deviation thus the value of z from the information above is: x=77 μ=58 σ=7 z=(77-58)/7=2.7143
