From an internship programme in which UWI students participated, Wall Street firms have concluded that there is an 18% chance the UWI students will perform better than the competition. What is the probability that in a random sample of 12 UWI students of that programme, 3 performed better than the competition?
Answer
it is a binomial distribution case with p = 0.18 and n = 12
we have to find the probability that exactly 3 performed better than competition
using the formula
setting p = 0.18, r = 3 and n = 12
Required probability is 0.2151

According to ILIR, 94% of eligible students participated in an internship during the previous school year. If we select a random sample of 5 ILIR students from then, what is the probability that: a) Between 2 and 4 of the students participated in an internship? b) At least 4 students participated in an internship? c) At most 4 students participated in an internship? When I do the problem, I'm using the formula: (n!/(x!*(n-x!))) * p^(x) * 1-p^(n-x). My answers seem...

A group consists of 18 students, 12 of which are females. If two students are selected at random from the group, one at a time and without replacement, what is the probability that the second student selected is female?
Suppose Wall Street securities firms paid out year-end bonuses of $125,500 per employee last year. We take a sample of employees at the ASBE securities firm to see whether the mean year-end bonus is less than the reported mean of $125,500 for the population. You wish to test the following claim ( H a ) at a significance level of α = 0.05 . H o : μ = 125500 H a : μ < 125500 You believe the population...
The reading speed of second grade students in a large city is approximately normal, with a mean of 91 words per minute (wpm) and a standard deviation of 10 wpm. Complete parts (a) through (f). (a) What is the probability a randomly selected student in the city will read more than 96 words per minute? The probability is nothing. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer...
7.13 A marketing survey is conducted in which students are to taste two different brands of soft drink. Their task is to correctly identify the brand tasted. A random sample of 200 students is taken. Assume that the students have no ability to distinguish be- tween the two brands. a. What is the probability that the sample will have between 50% and 60% of the identifications correct? b. The probability is 90% that the sample percentage is contained within what...
Students across the U.S. take the ACT test, which has scores that are normally distributed with a mean of 21 with a standard deviation of 5. If 250 students are randomly selected, what is the probability that at least 15 of them will score a 29 or better? A small college has an entering freshmen class of 600 students.

In a university class that includes 120 students, mostly non-traditional, the Mean age is 32, with a standard deviation 12 students, and with a normal distribution. Six of these students are international students What is the probability that, if one student is picked at a random, he/she be a teenager (12 to 19 years old)? You need to (somewhat) critically think about this before tackling it!! 1. What is the probability that if ONE student is selected at random, he/she...
