A simple random sample of 10 pages from a dictionary is obtained and the number defined words on each page is recorded. The sample mean is found to be 53.5 definitions per page and a standard deviation of 15.7 definitions per page. To support a claim that there are more than 70000 defined words is the same as the claim that the mean number of defined words on a page is greater than 48.0. Use a 0.05 significance level to test this 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 Define words, the claim that there are more than 70,000 to find words is the same as the claim that the mean number of Define words on a page is greater than 48.0. Use a 0.05 level significance level to test this claim. What does the results of suggest about the claim that they are more than 70,000 Define words in the dictionary? 50 ;34 ;84;67;57;78;48;46;69;77 no hypothesis mean equals 48.0 alternative hypothesis is greater than 48.0 test statistics=? critical values=?

Conduct the appropriate test. A simple random sample of size $n=40$ is drawn from a population. The sample mean is found to be $108.5,$ and the sample standard deviation is found to be $17.9 .$ Test the claim that the population mean is greater than 100 at the $\alpha=0.05$ level of significance.
