A college is going to administer an assessment test to incoming freshman. The test is going to be administered over the course of a month with 200 hundred students taking the exam the first weekend. The college computes the average score of the first 200 hundred students to be 85% with a standard deviation of 10%. Calculate a 95% confidence interval for the average score of all incoming freshman. (83.61, 86.38) (83.61, 86.39) (84.96, 85.04) (83.61, 86.30)

I need to see if I am doing these problems correctly. I am more of a handwritten person so if you can show me how to write these out I would appreciate it for our teacher only shows us how to use a calculator. Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.9 hours to be admitted into the hospital. The standard deviation for these 15 patients was 1.4 hours. What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use     The null and alternative hypotheses would be:       H0:H0:                   H1:H1:               The test statistic     =  (please show your answer to 3 decimal places.) The p-value =  (Please show your answer to 4 decimal places.) The p-value is     αα Based on this, we should…

A random sample of size n= 501 from a population whose parameter is p=0.14.   A. What is the mean of the distribution of sample means? Round the answer accurate to 2 decimal places.   B. What is the standard deviation of the distribution of sample means? Round the answer accurate to 2 decimal places.

E) what other questions might this raise about the results ?

Please assist and answer on questions D, E, F, G, H, and I on this problem.  Thank you.

1) If the data is IQ test scores, an individual with a negative z-score what IQ level would he have? 2

Hello. Can I get help on how to work this problem? Thank You!

There are 9 million enrollees in the Department of Veterans Affairs health care system. It wants doctors and nurses to treat pain as a “fifth vital sign” to be recorded along with blood pressure, pulse, temperature, and breathing rate. If you were to aid the VA in this situation, how would you measure a patient’s pain? How could this “fifth vital sign” be a potentially invalid measure? Answer each question with at least one paragraph of three complete sentences.
