For the population of 30 year-old men who later develop diabetes mellitus, the distribution of body mass index is approximately normal with unknown mean mu and standard deviation sigma. A sample of 25 30 year-old men who later developed diabetes mellitus had a sample mean body mass index of 25.0 kg/m2 and a sample standard deviation of 2.6 kg/m2. Estimate the mean body mass index, of the population of 30 year-old men who later developed diabetes mellitus, with the 95% confidence
Select one:
a. (23.93, 26.07)
b. (22.4, 23.93)
c. (22.4, 27.6)
d. (24, 26)

In the 1970s, 20 − 29 year old men in the U.S. had a mean body weight of 170 pounds and the standard deviation was 40 pounds. We test whether mean body weight in the population now differs by sampling 64 random men. Carry out a hypothesis test with α = 0.05 to determine if the sample provides convincing evidence that the population mean is 173

Suppose the distribution of serum cholesterol values in undergraduate men is approximately normally distributed with mean mu = 190 mg/dl and standard deviation sigma = 40 mg/dl. a) What is the probability of selecting someone at random from this population who has a cholesterol value that is less than 180? b) You take a simple random sample of n = 49 individuals from this population and calculate the mean cholesterol of the sample. Describe the sampling distribution of x-bar? c)...

Researchers were interested in estimating the mean body mass index (BMI) for 5 year old girls in a very large school district in Oklahoma. A random sample of size 61 five year old girls was drawn, and the sample mean BMI was found to be 17.4. Although BMI measurements are typically a little right-skewed, because of the reasonably large sample size, the researchers felt it was reasonable to use procedures based on the normal distribution. Based on previous information, they...
