HELP WITH QUESTIONS 1 AND 2 THAT GOES ALONG WITH PICTURE....

Question 2: What does the result suggest about the mean wake time of 102.0 min before the treatment? Does the drug appear to be effective?

(choose either or options for this question)

The confidence interval ( INCLUDES OR DOES NOT INCLUDE) the mean wake time of 102.0 min before the treatment, so the means before and after the treatment (ARE DIFFERENT OR COULD BE THE SAME)This result suggests that the drug treatment (DOES NOT HAVE OR DOES HAVE) a significant effect.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before
treatment, 23 subjects had a mean wake time of 102.0 min. After treatment, the 23 subjects had a mean wake time
of 97.1 min and a standard deviation of 20.1 min. Assume that the 23 sample values appear to be from a normally
distributed population and construct a 90% confidence interval estimate of the mean wake time for a population with
drug treatments. What does the result suggest about the mean wake time of 102.0 min before the treatment? Does
the drug appear to be effective?
Construct the 90% confidence interval estimate of the mean wake time for a population with the treatment.

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 + ...
