Determine the effects on the graph of the parent function f (x) = x2 when f (x) is replaced. 9. f(x) is replaced by f(x) + d where d = −2
10. f(x) is replaced by f(x − c) where c = 4
11. f (x) is replaced by a f (x) where a = 0.6
12. f(x) is replaced by f(bx) where b = 2

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.
