3. The mean and standard deviation of a normal distribution are 15 and 4 respectively. Find the raw score x that corresponds to z = -2.25
Answer:
equal probability. Its mean is 0.5 and its standard deviation is 112√≈0.2887 . 1.65 standard deviations below the mean is 0.5–1.6512√≈0.5–1.65×0.2887≈0.0237 . So there’s 2.37 % chance of getting a value 1.65 or more standard deviations below the mean of a uniform distribution (that’s true for all uniform distributions, not just the one from 0 to 1 ).
