Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate the mean score u of those who took the MCAT on your campus, you will obtain the scores of an SRS of students. The scores follow a Normal distribution, and from published information you know that the standard deviation is 10.8. Suppose that, unknown to you, the mean score of those taking the MCAT on your campus is 495. In...

The cumulative probability distribution shows the probability 10 O A. of two or more events occurring at once O B. that a random vaniable less than or equal to a particular value. O c. of all possible events occurring O D. that a random variable takes on a particular value given that another event has happened 11.

Some of the common medications to help people with insomnia
fall asleep include Ambien, Lunesta, and Sonata. Ambien CR is an
extended-release variation and is formulated so that an individual
will fall asleep within 30 minutes. The probability density
function for X, the time (in minutes) it takes to fall asleep after
taking an Ambien CR tablet, is given below.
0.05,
f(x) = -0.0025(x-30),
0,
(a) Verify that this is a valid probability density
function.

1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
