It is believed that 40% of all adults in Metro Manila are in favor of the death penalty for heinous crimes. Do we have reason to believe that the proportion of adults favoring death penalty heinous crimes is greater than 40% if in random sample of 150, 80 are in favor of death penalty. Use 0.05 level of significance. Step 1: Statement of the Hypothesis Step 2: Level of Significance Step 3: Computation Step 4: Decision and interpretation Step 5: Conclusion
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.
