Question

Using 0.05 level of significance and assuming that the data is normally distributed: • Test the claim which tells that the mean serum cholesterol is less than 200 mg/dL. Additionally, construct a 95% confidence interval for the mean serum cholesterol of the respondents.

VARIABLES:
a) "Exercise" = 0 stands for 'no' & 1 stands for 'yes'
b) "Serum cholesterol" = provided in mg/dL
c) "Weight" = provided in pounds
d) “Smoking status"
• 0 stands for 'does not smoke'
• 1 stands for 'smoke less than one pack per day'
• 2 stands for 'smoke one or more than one pack per day'
The given information below shows the result of health exam taken from 100 randomly
selected individuals who undergoes treatment for their high blood.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
