Question 1156371: The mean starting salary for college graduates in spring of 2018 was $43,200. Assume that the distribution of starting salaries follows the normal distribution with a standard deviation of $3500. What percent of the graduates have starting salaries:

a. Less than $38,000?

b. More than $45,000?

c. Between $38,000 and $45,000?

z=(x-mean )/sd
first is z<(38000-43200)/3500=-5200/3500=-1.49
probability is 0.0681
second is z>1800/3500 or 0.51. probability is 0.3050
third is the z between (-1.49 and +0.51) or the complement of the sum above
the answer for both is the same or 0.6269
