You take a random sample of 25 student athletes and measure their diastolic blood pressure. the sample mean is 70 (the units are mm hg) and the population variance = ď 2 (this will change in the parts of the question below). consider the null hypothesis that diastolic blood pressure is over 80mm hg versus the relevant alternative hypothesis (ha : ⵠ≤ 80). compute the p-value for each part below and state if you would reject the null at the î± = 4% level: a) ď 2 = 225 b) ď 2 = 900 4.1 using the information from # 4 a)â’b) above, calculate the p-value if the null hypothesis was that diastolic blood pressure equals 80mm hg versus the relevant alternative hypothesis (what is in each case, tell if you would you reject the null hypothesis at the î± = 4% level. a) b)
