Tom bought a new car in 2008 for $15,000. The table shows its value for each year from 2008 to 2012. Using the equation for the line of best fit, which is closest to the likely value of the car in 2016? Year Value A. $4000 2008 15,000 2009 13,800 B. $3700 2010 12,200 C. $3300 2011 10,600 D. $3000 2012 9,500
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.
