Hi,
For a particular sample of 77 scores on a psychology exam, the following results were obtained.
First quartile = 42 Third quartile = 69
Mean = 62, Median = 56
I. What score was earned by more students than any other score? by defn.
II. What was the highest score earned on the exam? , x =
III. What was the lowest score earned on the exam?
IV. According to Chebyshev's Theorem, how many students scored between 32 and 92? , = 76.23 or 76
V. Assume that the distribution is normal. Based on the Empirical Rul...
how many students scored between 52 and 72? OR 52
The empirical rule says that if you go 1 standard deviation out from the mean that you will capture 68 % of your data
