30% of a college campus commute. If 3 students are randomly selected from this campus, what is the probability that at least one of them commute?
Solution:
Using Excel,
P(X 1 ) = 1 - P(X < 0 )
=1- BINOM.DIST(0,3,0.30,TRUE)
= 0.6570
Probability = 0.6570

80% of students at a College live on campus. 120 randomly selected students at the college are surveyed and asked their living situation. Let p̂ be the proportion of students in the sample survey who report they live on campus. a) Find the mean and standard deviation of the sampling distribution of p̂. b) Use normalcdf with the sample proportion p̂ to determine the probability that at least 75% of the students in the survey live on campus.
80% of students at Merrimack College live on campus (normally— not during a pandemic). 120 randomly selected students at Merrimack are surveyed and asked their living situation. Let p̂ be the proportion of students in the sample survey who report they live on campus. a. Find the mean and standard deviation of the sampling distribution of p̂. b. Use normalcdf with the sample proportion p̂ to determine the probability that at least 75% of the students in the survey live...
In a randomly selected 100 students in a large college, 20 of them had at least one sibling. Does this provide strong evidence that more than 15% of college students in America have at least one sibling? Find the value of the test statistic (round off to first decimal place)
Suppose that 30% of all college students smoke cigarettes. A sample of 16 is selected randomly. . What is the probability that between 5 and 8 (both inclusive) students smoke? Round your answer to four decimal places.
Suppose that 30% of all college students smoke cigarettes. A sample of 14 is selected randomly. What is the probability that between 6 and 8 (both inclusive) students smoke? Round your answer to four decimal places.
25% of all college students major in STEM (Science, Technology, Engineering, and Math). If 33 college students are randomly selected, find the probability that a. Exactly 9 of them major in STEM. b. At most 10 of them major in STEM. c. At least 7 of them major in STEM. d. Between 5 and 10 (including 5 and 10) of them major in STEM.
At your college 30 % of all students are from out of state. If you randomly select 15 of these students, what is the probability that: A. All are from within the state? B. All from out of state? C. Exactly two are from within the state? D. At least 5 are from within the state? Please show how to work out the problem, it helps a lot. Thank you!
6. The college health center did a campus-wide survey of students and found that 18% of the students smoke cigarettes. A group of nine students randomly come together and sit at the same table on the plaza in front of the library. Find the probability that: (a) No student at the table smokes. (b) At least one student at the table smokes. (c) More than two students smoke. (d) From one to five smoke (including one and five).
Suppose two people are randomly selected from a class of 30 students. What is the probability that they have the same birthday? Round your answer to 3 significant digits
A recent study at a local college claimed that the proportion, p, of students who commute more than fifteen miles to school is no more than 15%. If a random sample of 275 students at this college is selected, and it is found that 55 commute more than fifteen miles to school, can we reject the college's claim at the 0.1 level of significance? Perform a one-tailed test. Then fill in the table below Carry your intermediate computations to at...
