Find the indicated probability. Express your answer as a simplified fraction unless otherwise noted. If one of the 87 flights is randomly selected, find the probability that the flight selected arrived on time. a b c d 9.A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness. Use p, the true percentage of the population that suffers from extreme shyness. H0: p 5.8% : p = 5.8% H0: p = 5.8% : p 5.8% 10.Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a two-tailed test is z = 1.95. 0.9744; fail to reject the null hypothesis 0.0512; fail to reject the null hypothesis 0.0512; reject the null hypothesis 0.0256; reject the null hypothesis 11.Evaluate the expression. 13! -13 4,790,016,000 169 6,227,020,800 12.The differences between two sets of dependent data are : 84, 85, 83, 63, 61, 100, 98.

Find the value of that corresponds to a confidence level of 95%. .05 1.645 1.96 2.575 17.The scores on a certain test are normally distributed with a mean score of 60 and a standard deviation of 5.

Thank you for using the site. I'll be happy to help you with these problems.

Do you have these problems in a Word document or PDF perhaps? It appears that there are figures and diagrams that are missing, and it also appears that the problem set is not complete as problem #18 seems to have been cut off.

If you have them in a document, you can attach it to your reply using the "Add a file" link, or you can upload it to a file-sharing website such as mediafire.com or sendspace.com. If you use one of those sites, simply copy the sharing link for your file, and then paste that into your reply.

If needed, it is also possible to arrange for you to be able to send the file to me by email. However, there is a small additional charge for that so perhaps that should be kept as a last resort option. Let me know if you would like to use that option though.

the response of a question should not allow the payment to process

I believe that we can overcome the issue about uploading the questions, if you can give me some information about what you have available to you. Do you have the problems in a document of some kind on your computer?
