Statistics students in Oxnard College sampled 11 textbooks in the Condor bookstore and recorded the number of pages in each textbook and its cost. The data are shown below: Number of Pages (xx) Cost(yy) 562 68.2 501 62.1 864 109.4 317 37.7 921 110.1 758 88.8 304 39.4 972 120.2 306 48.6 779 89.9 944 116.4 ˆyy^ = xx + . (Please show your answers to two decimal places) Use the model to estimate the cost when number of pages is 694. Cost = $ (Use the linear model with yor rounded coefficients and then round your answer to 2 decimal places.)
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Statistics students in Oxnard College sampled 11 textbooks in the Condor bookstore and recorded the number of pages in each textbook and its cost. The data are shown below:
| Number of Pages (xx) | Cost(yy) |
|---|---|
| 562 | 68.2 |
| 501 | 62.1 |
| 864 | 109.4 |
| 317 | 37.7 |
| 921 | 110.1 |
| 758 | 88.8 |
| 304 | 39.4 |
| 972 | 120.2 |
| 306 | 48.6 |
| 779 | 89.9 |
| 944 | 116.4 |
ˆyy^ = xx + . (Please show your answers to two decimal places)
Use the model to estimate the cost when number of pages is 694.
Cost = $ (Use the linear model with yor rounded coefficients and then round your answer to 2 decimal places.)
