The Italian government is giving Michelangelo's David a bath. In the newspaper, there was a photo of a person working on the statue. Their hand was half the size of the statue's hand. If the statue is 4.9m 3 and the density of marble is 2.76 g/cm 3 what is the mass? Express your answer in significant digits.

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.
