Question

The researcher wants to know if there is a significant difference between the group in their second test and those that didn’t take the drug in their overall mean of 3.35 in average respiratory scores with a standard deviation of .08. Is there a difference between the two means - does the drug work? Carry out 9 steps of hypothesis testing.

2. In studying the effect of a drug for treating patients with respiratory
problems, a researcher obtained a sample of 12 consenting patients, who,
after discussion with their doctor, chose a respiratory drug they would
receive. Patients' respiratory tests were assessed twice over a two-month
period after initiating the treatment. Research question: The researcher
wants to know if there is a significant difference between the group in
their second test and those that didn't take the drug in their overall mean
of 3.35 in average respiratory scores with a standard deviation of .08. Is
there a difference between the two means - does the drug work? Carry

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 + ...
