Question
A student wants to see if the number of times a book has been checked out of the library in the past year and the number of pages in the book are related. She guesses that the number of times a book has been checked out of the library in the past year will be a predictor of the number of pages it has. She randomly sampled 13 books from the library, test her claim at a 0.01 level of significance. number of times checked out 2 46 32 8 11 12 17 36 1 36 42 13 45 The correlation coefficient: (round to 3 decimal places) The equation y=a+bx is: (round to 3 decimal places) y= number of pages 204 449 374 318 331 The test value is: The hypotheses are: Ho: p= 0 (no linear relationship) HA:P 0 (linear relationship) (claim) Since a is 0.01 the critical value is -3.106 and 3.106 The p-value is: X 255 362 409 314 293 296 396 269 (round to 3 decimal places) (round to 3 decimal places)
