Step-by-step explanation:
Use a z-score table.
P(-0.85 < z < 1.15) = P(z < 1.15) − P(z < -0.85)
P(-0.85 < z < 1.15) = 0.8749 − 0.1977
P(-0.85 < z < 1.15) = 0.6772

67.72% probability of selecting a z score between -0.85 and 1.15
Step-by-step explanation:
Z - score
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Find the probability of selecting a z score between -0.85 and 1.15
This is the pvalue of Z = 1.15 subtracted by the pvalue of Z = -0.85
Z = 1.15 has a pvalue of 0.8749
Z = -0.85 has a pvalue of 0.1977
0.8749 - 0.1977 = 0.6772
67.72% probability of selecting a z score between -0.85 and 1.15
