Assume a normal distribution and find the following probabilities.
(Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)
(a)P(x<23|=26and=3)
enter the probability of fewer than23outcomes if the mean is26and the standard deviation is3
(b)P(x60|=40and=8)
enter the probability of60or moreoutcomes if the mean is40and the standard deviation is8
(c)P(x>34|=40and=5)
enter the probability of morethan34outcomes if the mean is40and the standard deviation is5
(d)P(21<x<25|=24and=3)
enter the probability of morethan21and fewer than25outcomes if the mean is24and the standard deviation is3
(e)P(x93|=80and=2.80)
enter the probability of93or moreoutcomes if the mean is80and the standard deviation is2.80
