A)Dendrites conduct signals toward the cell body and axons conduct signals away from the cell body B)Signals can travel in either direction in both axons and dendrites C)Axons conduct signals toward the cell body and dendrites conduct signals away from the cell body D)Signals will always travel in either direction in dendrites, but only away from the cell body in axons

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.18. what can you conclude? 2(0.18) = 0.36 < 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 18% of the time, so 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 82% of the time, so the test is not statistically significant. 0.18 > 0.05; the test is statistically significant. p = 1 - 0.18 = 0.82 > 0.05; the test is statistically significant.
