A scientist estimates that the mean nitrogen dioxide level in a city is greater than 24 parts per billion. To test this estimate, you determine the nitrogen dioxide levels for 31 randomly selected days. The results (in parts per billion) are listed to the right. Assume that the population standard deviation is 7. At a = 0.04, can you support the scientist's estimate? Interpret the decision in the context of the original claim. At the 4% significance level, there enough evidence to V the scientist's claim that the mean nitrogen dioxide level in the city is greater than 24 parts per billion.

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 = 58.5 words, s = 15.5 words. Given that this dictionary has 1460 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 47.9 words. Use a 0.05 significance level to test the claim that the mean number of words per page is greater than 47.9 words. What does the result suggest about the claim that there are more than 70,000 defined words?
