2. Rossi et al. (2013) studied the relationship between cholesterol level and hypertension. They compared
the total cholesterol measurements (mg/dl) for 15 patients with primary hypertension (PH) and another
15 patients who were normotensive (NT). The results are given below.
Patient Number Primary hypertensive patients Normotensive patients
1 207 177
2 172 179
3 241 194
4 185 206
5 134 173
6 222 189
7 180 194
8 276 168

11 183 188
12 214 200
13 259 179
14 152 142
15 210 222
Can we conclude that PH patients have, on average, higher total cholesterol levels than NT patients?

Anderson et al. (1990) studied the effect of diet on the level of low-density lipoprotein (LDL, the “bad” cholesterol) for a group of men with hypercholesterolemia. Half the subjects were given a diet that included corn flakes and the other half were given a diet that included oat bran. LDL was then measured after two weeks. Subjects were then crossed-over to the alternative diet for an additional two weeks. LDL was measured again. The LDL measurements are shown below. Test...

The objectives of a study by Skjelbo et al. were to examine (a) the relationship between Chloroguanide metabolism and efficacy in malaria prophylaxis and (b) the mephenytoin metabolism and its relationship to chloroguanide metabolism among Tanzanians. From information provided by urine specimens from the 216 subjects, the investigators computed the ratio of unchanged S-mephenytoin to R-mephenytoin (S/R ratio).

Cantor et al. (1988) reported a study of the relationship between the regular use of hair dye and the development of leukemia. The study entailed 577 leukemia patients and 1245 persons free from the disease (controls) who were questioned concerning their use of hair dye. Forty-three patients and 55 controls claimed to have had significant exposure to hair dye. a. Carry out the chi-square test of significance to test hair dye use (rate) differences between cases and control. b. Is...

Jachuck et al. (1982) report on an analysis of a certain drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability, a decline in energy, and a loss of sexual interest. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and relatives (typically spouses). Suppose that everyone agrees that the quality weight for hypertension is q = 0.8. That...

Janssen et al. studied Americans ages 60 and over. They estimated the mean body mass index of women over age 60 with normal skeletal muscle to be 23.1 with a standard deviation of 3.7. Using these values as the population mean and standard deviation for women over age 60 with normal skeletal muscle index, find the probability that 45 randomly selected women in this age range with normal skeletal muscle index will have a mean BMI (a) greater than 24....

Please answer all the questions. a) What is the probability that one randomly selected child between the ages of 2 and 6 years has a total cholesterol level between 150 mg/dL and 200 mg/dL? b) What is the probability that of 7...

R. Stichler et al. compared two methods of measuring treadwear in a paper. Eleven tires were each measured for treadwear by two methods: one based on weight, and the other on groove wear. The data, in thousands of miles, are in the table. Use the paired ?-test to answer the following: at the 5% significance level, do the data provide sufficient evidence to conclude that, on average, the two measurement methods give different results? Weight Method ------------------- Groove Method --------------...

Nakamura et al. studied subjects with medial collateral ligament (MCL) and anterior cruciate ligament (ACL) tears. Between February 1995 and December 1997, 17 consecutive patients with combined acute ACL and grade III MCL injuries were treated by the same physician at the research center. One of the variables of interest was the length of time in days between the occurrence of the injury and the first magnetic resonance imaging (MRI). We wish to know if we can conclude that the...
