3. A quarterback throws a football from a height of 6 feet with an initial velocity of 28 feet per second The height, , of the ball at time seconds can be represented by the equation ln(t) = - 16t ^ 2 + 28t + 6 If the ball is caught at 2 feet, find the range of the function

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.
