A survey which asked about study time and exam score has data as shown on the scatter plot. The least squares line was also graphed and the equation is below. e = 1.04 t + 38.4 100 90 80 70 60 10 20 30 40 50 60 50+ Study Time, t [minutes] For a student who studies for 28 minutes, use the equation to predict the exam score. Round to the nearest whole number. Select an answer Exam score, e [points]
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.
