Question

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the 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 is the same as the claim that the mean number of defined words on a page is greater than 48.0. Use a 0.10 level significance level to test this claim. What does the result suggest about the claim that there are more than 70,000 defined words in the dictionary? 77 40 84 50 62 65 39 44 78 81

a) Identify the test statistic

b) what is the critical value

A simple random sample of 20 pages from a dictionary is
obtained. The numbers of words defined on those pages are found,
with the results n=20 x=53.75 words, s=15.21 words. Given that
this dictionary has 1484 pages with defined words, the claim that
there are more than 70,000 defined words is equivalent to the
claim that the mean number of words per page is greater than 47.24
words. Use a 0.100 significance level to test the claim that the
mean...

A simple random sample of 20 pages from a dictionary is
obtained. The numbers of words defined on those pages are found,
with the results n = 20 , x overbar = 53.8 words, s = 15.2 words.
Given that this dictionary has 1452 pages with defined words, the
claim that there are more than 70,000 defined words is equivalent
to the claim that the mean number of words per page is greater than
48.2 words. Use a 0.101significance level...

Assume that a simple random sample has been selected from a
normally distributed population and test the given claim.
Use either the traditional method or P –value method as
indicated. Identify the null and alternative hypotheses, test
statistic, critical value(s) or P -value, and state the final
conclusion that addresses the original claim. A researcher wants to
test the claim that convicted burglars on average of 18.7 months in
jail. She takes a random sample of 11 such casas from...

A simple random sample of 10 pages from a dictionary is
obtained. The numbers of words defined on those pages are found,
with the results n=10, x=65.7 words, s=15.4 words. Given that this
dictionary has 1430 pages with defined words, the claim that there
are more than 70,000 defined words is equivalent to the claim that
the mean number of words per page is greater than 49.0 words. Use a
0.10 significance level to test the claim that the mean...
