4. The following table shows the number of absent time during Study the table and answer the following questions: 2020 for math classes. Not One time Two More than absent at times two times all Full time 42 24 10 3 student Part time 23 10 5 1 student 2020 and a. Draw pie chart showing the absence of full time students during comment on the graph. (show all steps) b. Find the total number of students' studied math in 2020. c. If one student is selected at random, then find probability of getting: A full time students and absent for more than two times. i. ii. A student absents for less than two times. iii. A full time student absents for one time or a part time student absent for two times. iv. A student absents for at least one time.
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.
