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=54.8 words, s= 16.1 words. Given that t dictionary has 1438 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 48.7 words. Use a 0.01 significance level to test the claim that the mean number of words per page is greater than 48.7 words. What does the result suggest about the claim that there are more than 70,000 defined words? Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Assume that the population is normally distributed.

Transcribed Image Text: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=54.8 words, s= 16.1 words. Given that th
dictionary has 1438 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 48.7
words. Use a 0.01 significance level to test the claim that the mean number of words per page is greater than 48.7 words. What does the result suggest about the claim that there are more
than 70,000 defined words? Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Assume that the population is
normally distributed.
What are the null and alternative hypotheses?
OA. Ho: H=48.7 words
H₁: <48.7 words
OC. Ho: H=48.7 words
H₁: >48.7 words
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
(Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
Ho. There is
evidence to support the claim that there
OB. Ho: μ>48.7 words
H₁: μ<48.7 words
O D. Ho: H=48.7 words
H₁: μ#48.7 words
70,000 defined words in the dictionary.
