In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally distributed,with a mean of 4.6 and a standard deviation of 2.6. Answer parts (a)-(d) below.(a) Find the probability that a randomly selected study participant's response was less than 4.The probability that a randomly selected study participant's response was less than 4 is(Round to four decimal places as needed.)

The salary of a recent graduate from a northeast university with an MBA follows a normal distribution with a mean starting salary of $78,000 with a standard deviation of $15,000. You apply the normal model and discover that approximately 7.1% receive a starting salary of more than $100,000. A university administrator surveyed a random sample of 450 of their recent graduates that earned an MBA. How many of these graduates would you expect to receive a starting salary of more than $100,000? Explain.
