What is the conclusion of the test if the level of significance is αα=0.10
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.

The p-value of the test is 0.0372. What is the conclusion of the test if the level of significance is αα=0.10?
- There is enough evidence to conclude that all five group means are significantly different from each other.
- There is not enough evidence to conclude that all five group means are sigificantly different from one another.
- There is enough evidence to conclude that at least one group mean is significantly different from others.
- There is not enough evidence to conclude that at least one group mean is significantly different from others.
- There is enough evidence to conclude that at most two group means are significantly different from each other.
- There is not enough evidence to conclude that at most two group means are significantly different from each other.
