The age of a students in a class is a normal random variable. There are 80 students in our class. I select 9 students randomly and calculate the mean of their ages (sample mean). I repeat this experiment 1,000,000 times. Then I calculate the mean and standard deviation of the 1,000,000 sample means that I measured; the calculated values are 22 and 4, respectively. What is the probability that the age of a randomly selected student in the class is...

Determine whether the random variable X has a binomial distribution. If it does, state the number of trials n . If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the number of students who missed the first exam. Choose the statement The random variable (?CHOOSE ONE?) a binomial distribution. Choose the statement that explains why does not have a binomial distribution. More than one may apply. A)...

This program will use the Random class to generate random temperatures (integers) between some minimum (inclusive) and some maximum (inclusive) values. You will need to calculate the minimum and maximum given a starting temperature integer and a possible change in temperature integer. (1) Copy the following method stub into your Temperature Predictor class and complete it according to the specifications described in the header comments. * Generates a random temperature (int) within a range when given the current temperature *...

You are playing a card came, and the probability that you will win a game is p = 0.39. If you play the game 95 times, what is the most likely number of wins? (Round answer to one decimal place.) = Let X represent the number of games (out of 95) that you win. Find the standard deviation for the probability distribution of X. (Round answer to two decimal places.) The range rule of thumb specifies that the minimum usual...

1.) In the previous question (the one about the multiple-choice quiz), the random variable X is binomial with parameters: n = 1/5, p = 15 n = 15, p = 1/2 n = 15, p = 1/5 n = 15, p = 0 2.) Assume that a procedure yields a binomial distribution with a trial repeated n=5n=5 times. Use technology to find the probability distribution given the probability p=0.164p=0.164 of success on a single trial. (Report answers accurate to 4...

In this section, first identify the random variable(s) and its/their range (=possible values it could attain). Use 6 decimal places for best accuracy when dealing with numerical data. Question 14 Take the following sample of student grades from a class: 70, 88, 91, 75, 79, 77, 70, 74, 81, 90 If these are assumed to represent the general pattern of the grades for the full class, use Chebychev’s inequality to give a lower bound on the probability that a given...
