Practice 1. Write an equation for each linear relationship after transforming y= x. a. dilation by a factor of b. dilation by a factor of 8 c. reflection across the x-axis d. translation down 6 units e. dilation by a factor of 2, then a translation up 3 units f. reflection across the x-axis, dilation by a factor of 3, and then a translation down 9 units 2. Use the graph of the linear relationship shown to complete each task. a. Write the equation of the line. b. Write the equation of the line after a translation down 8 units. Graph the line. 46+ 12- 8- c. Write the equation of the line after a translation up 8 units. Graph the line. 12 16
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.
