The z-scores that are the cutoffs are given as follows:
a. z = 1.645.
b. z = -1.96.
c. z = -0.51.
d. z = 0.
e. z = 0.
<h3>What is the z-score formula and what does it represent?</h3>
The z-score of a measure X of a variable that has mean given by and standard deviation represented by is given as follows:
- The z-score measures how many standard deviations the measure X is above(in case the score is positive) or below(in case the score is negative) the mean.
- From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.
For this problem, we have that:
- In item a, the cutoff is the 95th percentile, hence z = 1.645, which has a p-value of 0.95.
- In item b, the cutoff is the 2.5th percentile, hence z = -1.96, which has a p-value of 0.025.
- In item c, the cutoff is the 30.5th percentile, hence z = -0.51, which has a p-value of 0.305.
- In item d, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.
- In item e, the cutoff is the 50th percentile, hence z = 0, which has a p-value of 0.5.
