Question

What is the two-sample test formula?

Step 1: Testing the claim that the difference in means is equal for men and women. The two-sample t-interval test would be appropriate to compare which is the confidence interval test.

Step 2: Let p1 state the mean for the times of handwashing for men. Let p2 state the mean for the times of handwashing times for women. The difference in mean times of men and women are equal. The hypothesis is,

Null hypothesis: (Claim)

H0: p1 = p2

Alternative hypothesis:

Ha: p1 ≠ p2

Step 3: Two tail test ( p-value = twice the smaller of the proceeding left-tailed and right-tailed values)

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 + ...
