A p-value close to 1 means that it is very likely that the hypothesized and sample means are the same (assuming that they are the same), and a small p-value (for example 0.01) means it is unlikely (only a one in 100 chance) that such a difference would occur by chance (again, assuming that the two means …

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.

StatTalk Videos. These MyStatLab® videos and questions are optional. Dr. Vickers is a researcher at Memorial Sloan-Kettering Cancer Center, New York City. He is also an author of: What is a P-value anyway? More importantly, he is able to illustrate a statistical concept in everyday terms. The videos are brief, only a few minutes each.

p-value. A measure of how likely or unlikely the observed test statistic value is under the assumption that the null hypothesis is true. A low p-value indicates that the test statistic value is unlikely given the null hypothesis; we therefore

The p-value is labeled as “Sig.” in the SPSS output (“Sig.” stands for significance level). To find the correct “Sig.”, look in the section of the “Independent Samples Test” output labeled “t-test for Equality of Means” and you will find a column labeled “Sig. (2-tailed).”

The mean battery life is not equal to 4.5 hours since the sample mean is less than the hypothesized mean. Since the p-value > , the mean battery life is not equal to 4.5 hours. Since the p-value > , there is insufficient evidence to say the mean battery life is not equal to 4.5 hours.
