6. A University оf Sоuth Flоridа biologist conducted аn experiment to determine whether increаsed levels of carbon dioxide kill leaf-eating moths (USF Magazine, Winter 1999). Moth larvae were placed in open containers filled with oak leaves. Half the containers had normal carbon dioxide levels while the other half had twice the normal level of carbon dioxide. Ten percent of the larvae in the containers with “high” (twice the normal level) carbon dioxide levels died, compared to 5 percent in the containers with normal levels. Assume that 80 moth larvae were placed, at random, in each of the two types of containers. Is there enough evidence to conclude that the higher carbon dioxide level is effective in killing a higher percentage of leaf-eating moth larvae? (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (a) Which of the following best represents the hypothesis for Step 1 the hypothesis test?
7. Beаr gаllblаdder is used in Chinese medicine tо treat inflammatiоn. Due tо the difficulty of obtaining bear gallbladder, Chinese medical researchers are searching for a more readily available source. A study in the Journal of Ethnopharmacology (June 1995) examined pig gallbladder as an effective substitute for bear gallbladder. Twenty male mice were divided randomly into two groups: 10 were given a dosage bear bile and 10 were given a dosage of pig bile. All the mice then received an injection of croton oil in the left ear lobe to induce inflammation. Four hours later, both the left and right ear lobes were weighed, with the difference (in milligrams) representing the degree of swelling. Summary statistics are provided below: Bear Bile: n = 10 sample mean = 9.19 s = 4.17 Pig Bile: n = 10 sample mean = 9.71 s = 3.33 Assume that the populations of the difference of swelling for bear bile and pig bile ears are normally distributed. Do the data show that the mean degree of swelling of mice treated with bear bile is significantly less than the mean degree of swelling of mice treated with pig bile? (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.)
