Una tómbola contiene 3 bolitas numeradas del 1 al 3. Se extraen las bolitas al azar, una a una, y se forma un número de 3 cifras respetando el orden de
extracción de las bolitas. ¿Cuál es la probabilidad de que el número formado sea
mayor a 200?

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.
