Solution:-
Q8: What are the z-scores that mark the middle 95% of this distribution?
9) The raw score below the mean is - 1.96
p-value for the middle 95% below mean = 1 - 0.975
p-value for the middle 95% below mean = 0.025
z-score for the p-value(0.025) = - 1.96
10) The raw score above the mean is + 1.96.
p-value for the middle 95% above mean = 0.975
z-score for the p-value(0.975) = + 1.96
11) The median of this z-score distribution is 50.
Mean, median and mode are same for normal distribution.
