5) The probability that a typist makes 0, 1, 2, 3, 4, or 5 mistakes on a page are, respectively 0.09, 0.11, 0.24, 0.21, 0.17, 0.05. What is the probability that the typist makes three or more

mistakes mistakes on a page.

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.
