Whoever gets it gets brainliest answer betty picks 4 random marbles from a bowl containing 3 white, 4 yellow and 5 blue marbles. the probability that exactly 1 of the 4 marbles drawn in blue is {options: 0.0707 0.2135 0.3535 0.6465} the probability that at least 1 of the 4 marbles drawn is white is {options: 0.2181 0.2546 0.5090 0.7455}

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.
