      In the z-table, 1.75 standard deviations corresponds to a probability of 0.4599, so our one-tailed p-value is approximately 0.5 – 0.4599 = 0.0401. Since this value is smaller than 0.05, we reject the null hypothesis, and conclude that the true population mean is less than 2.8 feet.

      probability in the tail? t. Appendix B.2: The t Distribution. Table 9-1 (p. 285). A portion of the t-distribution table. The numbers in the table are the values of t that separate the tail from the main body of the distribution. Proportions for one or two tails are listed at the top of the table, and df values for t are listed in the first column.

      Table 2: We recast Table 1 in terms of probability. Adding up the first column tells you the probability P(D) that the selected person lives in the dorms: 24/200 + 1/200 = 25/200 = .125. In parallel fashion, the probability of not living in the dorms is .18 + .695 = .875.

      Figure illustrates the calculation of the P-value. From Table IV we find. The probability in each tail is 1-0.8106 = 0.1894, and the P-value is . Since P-value is larger then , we do not reject at the level . Figure The P-value for Example 8.2. Example A coin was tossed n=4040 times and we observed X=1992 tails.

      Step 2: According to column C in the unit normal table, the proportion in the tail beyond z = 0.70 is p = 0.2420. Step 3: Note that this proportion includes the section that we want, but it also includes an extra, unwanted section located in the tail beyond z = 1.70. Step 4: Locating z = 1.70 in the table, and reading across the row to column C ...
