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 researcher wants to test whether the mean weight of all high school students in the state (u) would be 70 kg or not.
So, the null and the alternative hypotheses for the test the researcher wants to conduct are:
O A. The researcher's null hypothesis is Ho:=70 and the alternative hypothesis is HA: Hz70.
O B. The researcher's null hypothesis is H:=70 and the alternative hypothesis is H us70.
O C. The researcher's null hypothesis is Ho: H70 and the alternative hypothesis is HA:ut70.
