We find the P-value by comparing 0.654 to critical values for the t(132) distribution and then doubling p because the alternative is two-sided. Table D (for 100 degrees of freedom) shows that 0.654 does not reach the 0.25 critical value, which is the largest entry for p in this table. The P-value is therefore greater than 0.50.

X B(n, p), read, the random variable X has a binomial distribution with parameters n trials, and probability of a success is p. Example: Find probability of at most k = 3 success from B(n = 7, p = 0.4). Using any Binomial table, one should get: P[k 3] = 0.7102. Using The P-values for the Popular Distributions JavaScript, one gets:

(i) Since this is an upper tailed test, reject H0 if t ( t(;n-1= t0.05;8 =1.86 or if the P-value=P(t>3.5764) is less than (=0.05. Notice that test statistics, 3.5764 is large than 1.86. (ii) 0.001

(ii) P-value =P(t>0.4978) > 0.10 by looking at the t-table with df=7. Since the P-value > (=0.05, fail to reject H0. Conclude that the average mileage of shaft wear is not larger than 3.5.

If an ANOVA is statistically significant report the p value of the test in the text and then include and describe a table that shows the post hoc analysis. ANOVA p. ost-hoc analysis table. Nicol and Pexman (2010) show two versions of how to do post hoc tables (Example tables 1 and 2).

To interpret the t-test results, all you need to find on the output is the p-value for the test. To do an hypothesis test at a specific alpha (significance) level, just compare the p-value on the output (labeled as a “Sig.” value on the SPSS output) to the chosen alpha level. Alternatively, you could just report the p-value, rather than ...
