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. ?...
A certain state has the highest high school graduation rate of all states at 85%. A. In a random sample of 10 high school students from the state, what is the probability that 8 will graduate? B. In a random sample of 10 high school students from the state, what is the probability than 7 or fewer will graduate? C. What is the probability that at least 8 high school students in our sample of 10 will graduate? Show work...
in a class of 40 students, 22 have taken the course before either at the high school or college levels. If we pick 5 students; a. create a probability distribution for the number of students who have taken the same course (C). b. What is the probability that at most 3 have taken the same course before c. Mean d. Variance e. standard deviation
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...
The scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=556.6 and standard deviation σ=27.7.(a) What is the probability that a single student randomly chosen from all those taking the test scores 562 or higher?For parts (b) through (d), consider a simple random sample (SRS) of 35 students who took the test.(b) What are the mean and standard deviation of the sample mean score x̅x̅, of 35 students?The mean...
The scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=557.1 and standard deviation σ=29. (a) What is the probability that a single student randomly chosen from all those taking the test scores 562 or higher? For parts (b) through (d), consider a simple random sample (SRS) of 35 students who took the test. (b) What are the mean and standard deviation of the sample mean score x¯, of...
