TABLE 6-2 John Has Two Jobs. for Daytime Work at a Jewelry

question 38

Short Answer

TABLE 6-2
John has two jobs. For daytime work at a jewelry store he is paid $15,000 per month, plus a commission. His monthly commission is normally distributed with mean $10,000 and standard deviation $2,000. At night he works as a waiter, for which his monthly income is normally distributed with mean $1,000 and standard deviation $300. John's income levels from these two sources are independent of each other.
-Referring to Table 6-2, the probability is 0.75 that John's commission from the jewelry store is less than how much in a given month?
