Leatherback turtles typically nest in the fall and winter months. Biologists have been tracking changes in sea temperatures and current shifts in the waters that a population of these sea turtles inhabits. They want to know if there has been a change in the distribution of nesting months for this population compared to what it was 5 years ago. They compute a test statistic of 8.1445 and select a critical value of 7.815. What is the correct conclusion?

Fail to reject the null hypothesis. There is not enough evidence to support the claim that the distribution has changed.

    Nitrate, an inorganic chemical, is a drinking water contaminant which is considered safe for human consumption as long as Nitrogen levels in the water are under 10 MCLG. A local library near a sewage plant is concerned that their public water fountain “tastes funny,” and they hypothesize that sewage runoff has affected the quality of their water. An EPA worker randomly tests 40 one-ounce samples of drinking water at the public water fountain and finds that the mean Nitrogen content...

    The mean age when smokers first start is 13 years old with a population standard deviation of 2 years. A researcher thinks that the smoking age has significantly changed since the invention of ENDS—electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 30 smokers found that their mean starting age was 12.2 years old. Do the data support the claim at the 5% significance level?...

    In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. In environmental studies, sex ratios are of great importance. Wolf society, packs, and ecology have been studied extensively at different locations in the U.S. and foreign...
