Give the null and alternative hypothesis of

The following are the laboratory results in hemoglobin of 10 male (X1) and 10 female(X2) patients. Test the null hypothesis that there is no significant difference between the hemoglobin of male and female patients. Use the t -test at 0.05 level of significance.

As part of the National Health Survey conducted by the Department of Health and Human Services, perceptions on the attitude and practices of vaccine were obtained for females aged 18-30 before and after intervention. Listed below are sample mean results. Is there sufficient evidence to support the claim that there is a difference in the attitude and practice between before and after intervention? Use a 0.05 significance level.

A researcher determines the BMI index of geriatrics from Tondo. Using 0.05 level of significance, is the BMI index of geriatrics are within the accepted norm (21)?

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 + ...
