#1) a normal distribution has a mean of 101 and a standard deviation of 4.2. what is the z-score of 105?

1 answer:

5 0

Step-by-step explanation:

z = (specific score - mean) / standard deviation

in our case

z = (105 - 101)/4.2 = 4/4.2 = 0.952380952... ≈ 0.95

as z-tables usually round the z-scores to hundredths.
