normal distributionto a normal distribution to find the probabilities and apply the properties of the normal. To do this, we use the z score.standard deviationsbetween an observation and the mean of a data set.normal random variable, if you find a Z-score for a value (i.e. normalize the value), the random variable will be transformed into a standard random variable and you can find the probability by using standard tables.standard curveto the right of the z-value is 0.75, then the area under the curve to the left of that z-value is 0.25.closest zoneto 0.2500 is 0.2514. The z value associated with this is -0.67.Answer:0.7734 or 77.34 percentStep-by-step explanation:
