The mean score for a standardized test is 1700 points. the results are normally distributed with a standard deviation of 75 points. what is the z score test result of 1300 points?

z score is 1.33 approximately.

Step-by-step explanation:

Given:

mean score= 1700  points

standard deviation= 75 points

value of interest =1300 points

To Find:

z score=?

Solution:

z-score:

A z-score describes the position of a raw score in terms of its distance from the mean when measured in standard deviation units. The z-score is positive if the value lies above the mean, and negative if it lies below the mean.

The formula to solve for z-scores is:

------------------------------------(1)

where,

X is the value of interest,

μ is the mean of the normal distribution,

σ is the standard deviation of the normal distribution.

Substituting the values in the equation (1), we have

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
