1. Suppose a random variable, x, arises from a binomial experiment. If n=22, and p = 0.85, find the following probabilities using the binomial formula. Show calculator command used. a. (2 pts) P(x = 18) = b. (2 pts) P(x < 3) = c. (2 pts) P(x> 20) =

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. You are interested in the mean score, μ , among the general population on this subsection. The website reports that μ is 145, but you have good reason to believe that μ is less than 145. You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is 139 and that the standard deviation of their scores is 28. Based on this information, complete the parts below. (a) What are the null hypothesis H0 and the alternative hypothesis H1that should be used for the test? H0: H1: (b) Suppose that you decide to reject the null hypothesis. What sort of error might you be making?   ▼(Choose one)   (c) Suppose the true mean score among the general population on the subsection is 136. Fill in the blanks to describe a Type II error. A Type II error…

Hi! I pretty much don't understand this problem that was presented on my Statistics class

If there is  someone that can please assist me! I have posted this statistics question 3 times and they keep saying it is a writing assignment. THIS QUESTION IS NOT A WRITING ASSIGNMENT. It is a STATISITCS problem. i am stuck and confused and just needing to see how you solve this! if you do not know how to do it then please leave it for someone else but this is NOT a writing assignment! i will also be glad to rate your work!

Write up your results as you would see them in a research paper. Be sure that you include the means and standard deviations for each group in your write-up, as well as a sentence or two explaining the results

One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. You are interested in the mean score, μ, among the general population on this subsection. The website reports that μ is 140, but you have good reason to believe that μ differs from 140. You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection is 146 and that the standard deviation of their scores is 22. Based on this information, complete the parts below. A. What are the null hypothesis H0 and the alternative hypothesis H1 that should be used for the test? H0: H1: B. Suppose you decide to reject the null hypothesis. Would you be making a type I or type II error?
