Choose the function that shows the correct transformation of the quadratic function shifted two units to the right one unit up. ƒ( x) = ( x - 2) 2 - 1
ƒ( x) = ( x + 2) 2 - 1
ƒ( x) = ( x - 2) 2 + 1
ƒ( x) = ( x + 2) 2 + 1

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.
