Answer:
0.3051
Explanation:
mean (μ) = 20.8, standard deviation (σ) = 5.6 and the number of samples (n) = 36 scores.
Z score also known as standard score is used in probability to measure the number of standard deviations by which the value of what is being measured is above or below the mean. It is given by the equation:
Z score (z) =
For x = 21.6,
From the probability table:
P(x < 21.6) = P(z < 0.86) = 0.3051 = 30.51%
The probability that the mean score for the sample is less than 21.6 = 30.51%
