In a certain class 28% of the students are left handed suppose that a random sample of 71 students is selected find the mean number of left handed students in the class
solution
given that,
n = 71
p = 0.28
mean= n * p =71 *0.28=19.88
answer =mean = 19.88

The proportion of left-handed people in the general population is about 0.1. Suppose a random sample of 225 people is observed. The proportion of left-handed people in the general population is about 0.1. Suppose a random sample of 225 people is observed. Using our 'rule of thumb; can we use normal approximation values for this sampling distribution? Yes + np = 22.5 and ng= (Click to view hint) What is the mean of the sample proportion? др (Click to hide...
NAME: 7. (15 points.) Left-handed people are more prone to accident-related injury than right-handed people Among a certain population of college students, the number of injuries X reported by a given student is a Poisson random variable; left-handers (L) report injuries at a handers (R) at a rate of 0.15 per year, 15% of the students are left-handed. rate of 0.25 per year, and right- (a) What is the probability that a randomly selected student is injured exactly twice this...
Suppose we know that the probability that a student is left handed is 0.27. Given our sample of 43 students selected at random, what is the probability that: Exactly 8 students are left handed. More than 20 students are left handed. At most 5 students are left handed.
The proportion of left-handed people in the general population is about 0.10.1. Suppose a random sample of 225225 people is observed.

Approximately 10% of people in the world are left-handed, so P(a person is left handed) = 0.1. Suppose we have a class of 15 people and UHD is interested in how many left-handed desks the class will need, so we define a random variable X, the number of left-handed people in the class. 1. What distribution family does this situation belong to? What is (are) the parameter(s)? 2. What is the probability that none of the students will be left...
3. Suppose there are 100 students in your accounting class, 10 of whom are left-handed. Two students are drawn at random. Draw the probability tree and insert the probability for each branch. a. What is the probability of the following events? b. Both are right-handed? c. Both are left-handed? d. One is right-handed and the other is left-handed? At least one is right-handed? oo b е. 4 Suppose you flip eight fair coins. What is the probability of flipping exactly...
Suppose that 10% of students are left-handed. a) In a study group of 6 students, find the exact probability that at most 1 of them is left-handed. b) In a classroom of 60 students, find an approximate probability that at most 10 of them are left-handed.
Suppose that n students are selected at random without replacement from a class containing 28 students, of whom 8 are boys and 20 are girls. We assume that 0 < n < 28. Let X denote the number of boys that are obtained. Answer the following questions: a (4 marks) State the distribution of X, with parameters b (1 mark) Write down the possible values of X c (1 mark) Express E(X) in terms of n. d (4 marks) For...
Suppose that a certain college class contains 47 students of these, 28 are sophomores, 27 are business majors, and 8 are neither. A student is selected at random from the class. (a) What is the probability that the student is both a sophomore and a business major? (b) Given that the student selected is a business major, what is the probability that he is also a sophomore? Write your responses as fractions. (If necessary, consult a list of formulas.)
Assume that 15% of people are left-handed. Suppose 16 people are selected at random. Answer each question about right-handers below. a) Find the mean and standard deviation of the number of right-handers in the group. b) What's the probability that they're not all right-handed? c) What's the probability that there are no more than 10 righties? d) What's the probability that there are exactly 7 of each? e) What's the probability that the majority is right-handed?
