The following ANOVA table, based on information obtained for three samples selected from three independent populations that are normally distributed with equal variances, has a few missing values. a. Find the missing values and complete the ANOVA table. Round your answers for the sum of squares and the mean square to four decimal places. Round your answer for F to two decimal places. Degrees of Freedom Sum of Squares Value of the Test Statistic Source of Variation Mean Square Between 2 19.2813 Within 89.3677 Total 12 b. Using a = 0.01, what is your conclusion for the test with the null hypothesis that the means of the three populations are allequal against the alternative hypothesis that the means of the three populations are not all equal? The means are the same the same eTextbook a not the same
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.
