Chapter 6, Problem 9E
Suppose that you wake up in the morning with all the symptoms of a head cold. You take a cold pill and eat a big bowl of your mother’s chicken soup. By midday your cold symptoms are gone, and you are feeling much better. Can you conclude that the chicken soup cured your cold? Explain why or why not.

You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients
with the flu and say that nausea is a side effect if people become nauseous. However, past research
indicates that about 30% of people who get the flu experience nausea, and you believe that the percentage
of those who experience nausea while having the flu and taking Tamiflu will be greater than 30%, which
would indigate that nausea is a side effect of Tamiflu.
If you are going to test this claim at the 0.05 significance level, what would be your null and alternative
hypotheses?

If you lower the concentration of cholesterol in the blood, your risk of developing heart disease can be reduced. Being overweight and/or physically inactive increases the concentration of cholesterol in your blood. Both exercise and weight loss can reduce cholesterol concentration. However, it is not known whether exercise or weight loss is best for lowering cholesterol concentration. Therefore, a researcher decided to investigate whether an exercise or weight loss intervention is more effective in lowering cholesterol levels. To this end, the researcher recruited a random sample of inactive males that were classified as overweight. This sample was then randomly split into two groups: Group 1 underwent a calorie-controlled diet and…arrow_forward
- As humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more.
