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.
Statistics students in Oxnard College sampled 9 textbooks in the Condor bookstore and recorded the number of pages in each textbook and its cost. The bivariate data are shown below:
| Number of Pages (xx) | Cost(yy) |
|---|---|
| 272 | 52.08 |
| 617 | 103.38 |
| 628 | 94.92 |
| 702 | 107.28 |
| 624 | 107.36 |
| 572 | 93.08 |
| 571 | 104.94 |
| 361 | 67.54 |
| 523 | 81.22 |
A student calculates a linear model
yy = xx + . (Please show your answers to two decimal places)
Use the model to estimate the cost when number of pages is 689.
Cost = $ (Please show your answer to 2 decimal places.)
