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 of the hypothesis test?
25 yeаr оld femаle with а histоry оf obesity but no other PMH reports irregular menstrual periods and an inability to conceive. The patient reports she gets her periods only few times a year. Each menstruation typically last for a few weeks. Last LMP was few months ago. The patient also reports she has been trying to get pregnant for about 6 months with no luck. The patient denies any recent significant weight loss or weight gain. On exam, patient is no distress. She is significantly overweight. (+) visible facial hair. Skin is significant for diffuse acne. On pelvic exam: cervix is closed with no lesions, uterus non-tender, no adnexal masses, no pelvic motion tenderness. Otherwise, exam is unremarkable. VS: BP: 120/70 mmHg Rt arm sitting; HR:70 bpm, T: 98.6F oral, RR: 16 bpm unlabored. Please provide differential diagnosis for this presentation (list at least 5) AND what imaging would be indicated for this case.
