A Z-Score allows us to calculate how much … Degrees of Freedom For Z-Test and T-Test. Z-tests use standard normal distribution … Z-Test Vs T-Test. Z-Test are used when the sample size exceeds 30. As Z-Test … A professor's exam scores are approximately distributed normally with mean 80 and standard deviation 5. Only a cumulative from mean table is available. • What is the probability that a student scores an 82 or less? P ( X ≤ 82 ) = P ( Z ≤ 82 − 80 5 ) = P ( Z ≤ 0.40 ) = 0.15542 + 0.5 = 0.65542 {\displaystyle {\begin{aligned}P(X\leq 82)&=P\!\!\left(Z\leq {\frac {82-80}{5}}\right)\\&=P(Z\leq 0.40)\\[2pt]&=0.15542+0.5\\[2pt]&=0.65542\end{aligned}}}
