Which of the following statements regarding Pascal's triangle are correct?
A. The method for generating Pascal's triangle consists of adding adjacent terms on the preceding row to determine the term below them.
B. The nth row gives the coefficients in the expansion of (x + y)n.
C. Pascal's triangle can be used to expand binomials with positive terms only.
D. The nth row gives the coefficients in the expansion of (x + y)n-1.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
