The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a=0.05, and (c) a=0.10. P= 0.0545 (a) Do you reject or fail to reject H, at the 0.01 level of significance? O A. Reject H, because the P-value, 0.0545, is less than a= 0.01. O B. Fail to reject H, because the P-value, 0.0545, is greater than a = 0.01. O C. Fail to reject H, because the P-value, 0.0545, is less than a = 0.01. O D.

How would you report the results? The derived t = 0.02 was not significant at p = .05 with df = 10. Therefore, Ho was not rejected, and it was concluded that the mean pretest score for students at the beginning of the semester (18.27) was not different than the mean posttest score for students at the end of the semester (22.00), t(10) -= 0.02, p .05. In terms of the research question, it appears that the curriculum was not effective in promoting learning.
Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about μ = 28 ml/kg.† Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows. 33 24 41 36 31 38 28 The sample mean is x ≈ 33.0 ml/kg. Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and σ = 4.75. Do the data indicate that Roger's red blood cell volume is different (either way) from μ = 28 ml/kg? Use a 0.01 level of significance. (c) Find (or estimate) the P-value.
