Question

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 = 0.01

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?

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 pages of my dictionary was collected.
These are the number of words defined on each page. Find the
measures of central tendency: mean, median, and mode. 51 63 63 43
43 43 69 43 39 53 63 There are 1749 pages. Estimate the total
number of words in the dictionary. Is the estimate likely to be an
accurate estimate of the total number of words in the English
language?

A data set lists earthquake depths. The summary statistics are
n=500, x =5.77 km, s=4.75 km. Use a 0.01 significance level to
test the claim of a seismologist that these earthquakes are from a
population with a mean equal to 5.00. Assume that a simple random
sample has been selected. Identify the null and alternative
hypotheses, test statistic, P-value, and state the final
conclusion that addresses the original claim.
a. Determine the test statistic.
b. Determine the P-value
