Suppose that you are in a class of 32 students and it is assumed that approximately 18% of the population is left-handed. (Give your answers correct to three decimal places.) (a) Compute the probability that exactly five students are left-handed. (b) Compute the probability that at most four students are left-handed. (c) Compute the probability that at least six students are left-handed.

EURLIR . WRITINGROOR ILALAR Suppose the distribution of the time X (in hours) spent by students at a certain university on a particular project is gamma with parameters a-40 and B-2 Because a is large, it can be shown that X has approximately a normal distribution. Use this fact to compute the approximate probability that a randomly selected student spends at most 115 hours on the project. (Round your answer to four decimal places.) Need Help? Read It Take a...

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...

Consider the approximately normal population of heights of male college students with mean μ = 67 inches and standard deviation of σ = 3.1 inches. A random sample of 16 heights is obtained. (a) Describe the distribution of x, height of male college students. skewed right approximately normal skewed left chi-square (b) Find the proportion of male college students whose height is greater than 67 inches. (Give your answer correct to four decimal places.) (c) Describe the distribution of x,...
