Stay in school: In a recent school year in the state of Washington, there were 320,000 high school students. Of these, 154,000 were girls and 166,000 were boys. Among the girls, 39,000 dropped out of school, and among the boys, 10,300 dropped out. A student is chosen at random. Round the answers to four decimal places.(a) What is the probability that the student is male?(b) What is the probability that the student dropped out?(c) What is the probability that the...
Here is data on the flow of students through a school 70% of freshmen pass and become sophomores, 20% fail and repeat as freshmen, 10% drop out 80% of sophomores pass and become juniors, 10% fail and repeat as sophomores, 10% drop out 80% of juniors pass and become seniors, 10% fail and repeat as juniors, 10% drop out 84% of seniors pass and graduate, 6% fail and repeat as seniors, 10% drop out Treat this as a 6-state Markov...
U.S. schools face an ongoing challenge: as students get closer to high school graduation, their enthusiasm for school falls. A Gallup poll in June 2017 has discovered that fifth graders are most engaged with school, while 11th graders are least. The latest Gallup poll showed that only 32% of 11th graders are engaged in school. Assume this value represents the population proportion. Suppose we randomly sample 150 11th graders in the U.S. and ask them their engagement in school. ?...
In a recent school year in the state of Washington, there were 325,000 high school students. Of these, 156,000 were girls and 169,000 were boys. Among the girls, 54,500 dropped out of school, and among the boys, 10,400 dropped out. A student is chosen at random. Round the answers to four decimal places.

Assume that any student has a 25% chance of getting into a certain college. Let the random variable X denote the number of students (from a total of 5 students who apply) who get into the school. For the following problems do not use calculator commands. a. What are the parameters n and p for the distribution? b. What is the expected number of students (out of the 5) who will be accepted to the school? c. Find the standard...
