Test the claim below about the mean of the differences for a population of paired data at the level of significance a. Assume the samples are random and dependent, and the populations are normally distributed. Claim: Ho<0; a=0.01. Sample statistics: d = 1.8, Sa = 3.4, n = 13 Identify the null and alternative hypotheses. Choose the correct answer below. 0 O B. Ho Hd < 0 Ha Ha 20 OD. Ho Hd = 0 O A. Ho Hd >...
A random sample of size n = 13 obtained from a population that is normally distributed results in a sample mean of 45.2 and sample standard deviation 12.6. An independent sample of size n=17 obtained from a population that is normally distributed results in a sample mean of 51.1 and sample standard deviation 14.9. Does this constitute sufficient evidence to conclude that the population means differ at the a= 0.10 level of significance? Click here to view the standard normal...
Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify null and alternative hypotheses, test statistic, critical value(s), and state the final conclusion that addresses the original claim. A simple random sample of pages from a dictionary is obtained. Listed below are the numbers of words defined on those pages. Given that this dictionary has 1459 pages with defined words, the claim that there are more than 70,000 defined words...
