Question
CHAPTER 22 #11 (2 pts. Given the convention of declaring that a result is statistically significant if the p- value is 0.05 or less, what decision would be made in each case? 1. p-value 0.35 (i) reject the null hypothesis (i) do not reject the null hypothesis 2. p-value 0.04 (i) reject the null hypothesis (ii) do not reject the null hypothesis #12a (i pt.) In previous chapters, we learned that researchers have discovered a link between vertex baldness and heart attacks in men. State the null and alternative hypotheses used to investigate whether there is such a relationship.Explanation / Answer
11)
statistically significant - p-value is 0.05 or less than 0.05
a) p-value = 0.35 , since p-vlaue is greater than 0.05 , we do not reject the null hypothesis
b)p-value = 0.04, since p-vlaue is less than 0.05 , we reject the null hypothesis
