Lacey is planning a beach vacation for next month. She compares the weather at two beaches during the
same month last year. At the first beach, it rained 5 out of 30 days. At the second beach, it rained 10% of
the days. Based on this experimental data, which beach has a better chance of being dry? Complete the
explanation. Round your answer to the nearest percent if necessary.
The second 7 beach has a better chance of being dry.
At the first beach, it rained about 75
% of the days.

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.
