Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two
independent test groups. The first group consisted of 10 people with the illness, and the second group consisted of 11 people with the illness. The first group
received treatment 1 and had a mean time until remission of 194 days, with a standard deviation of 9 days. The second group received treatment 2 and had a
mean time until remission of 188 days, with a standard deviation of 6 days. Assume that the populations of times until remission for each of the two treatment
are normally distributed with equal variance. Can we conclude, at the 0.01 level of significance, that the mean number of days before remission after treatmen
1, u1, is greater than the mean number of days before remission after treatment 2, µ,?
Perform a one-tailed test. Then complete the parts below.
Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of
formulas.)

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 + ...
