The graph depicts the dose response curves for three common bacteria and a newly
discovered bacterium found in streams near certain agricultural properties. If all four
of the bacteria species shown in the graph are equally likely to contaminate
agricultural products at a dose of 102 CFU, regulating which of the following species
would have the greatest effect in reducing the likelihood of illness in humans?

Indicate whether the scenario below is safe or unsafe: when storing a flammable liquid, you decide to separate it from other materials by a fire wall.

Reread lines 158-169. why does atlas beg perseus to show him medusa’s head? cite explicit textural evidence in your response.

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.
