Problem 3 The accompanying table lists pulse rates. Use a 0.05 significance level and apply the methods of Factorial Analysis of Variance. Pulse Rates for Gender and Age Under 30 Years of Age Over 30 Years of Age Female 77 104 80 63 61 97 83 97 90 96 75 75 72 66 71 79 63 73 74 55 Female Male 61 80 56 68 68 74 75 69 63 57 46 71 63 65 89 79 59 57 64 61 Male 1) State the null and alternative hypotheses in the test for the effect of an interaction between row and column factors. 2) Find the value of the critical value Fo
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
