sketch the sampling distribution and show the area corresponding to the P-value. a b P -value 0-3 -2 -1 1 2 O-3 -2 0 1 2 3 C P-value P-value O-3 -2 -1 0 2 0-3 -2 -1 0 2 (d) Based on your answers in parts (a) to (c), wil you reject or fall to reject the null hypothesis? Are the data statistically significant at level a? O AL the a - 0.01 level, we reject the null hypothesis and condude the data are statistically significant. O) At the a = 0.01 level, we reject the null hypothesis and condude the data are not statistically significant. At the a - 0.01 level, we fail to reject the null hypothesis and condude the data are statisticaly significant. At the a - 0.01 level, we fail to reject the null hypothesis and condude the data are not statistically significant. (e) State your conclusion in the context of the application. There is sufficient evidence at the 0.01 level to condude that Roger's average red cel volume differs from the average for healthy adults. There is insufficient evidence at the 0.01 level to conclude that Roger's average red cell volume differs from the average for healthy adults
