estion 1 3 points Save Answer Which of the following statement(s) are TRUE: (a) When doing a Hypothesis Test for a Population proportion the Confidence Interval Method and the (b) If the Correlation Coefficient is positive then the slope of the corresponding Regression Line is (c) The claim made in the Null Hypothesis corresponds to "no change" (d) If the Test Statistic of the observed sample mean falls in the Critical Region then this Test Statistic is (e) If there is a stro P. Value Method will always have the same conclusion positive. not significant ng correlation between the Explanatory and Response variables then a change in the Explanatory variable MUST CAUSE a change in the Response Variable (6 When the x-axis variable and the y-axis variable of a scatterplot are interchanged then the value of the Correlation Coefficient will not change e The hyothes Treg for the diffrence of two Population proportions conceptuailyuses a Sampling Distribution having a mean of zero b,c,f,g Oa, d, e All the statements are FALSE

Explanation / Answer

a. This will depend on the alpha used. Hence False

b. This is true as slope is positive means for increase x there is increase in y which means positive correlation, hence answer is True

c. Null hypothesis is for equality hence answer is True

d. It test statistics falls in critical region then its significant. So False

e. Correlation does not guarantee causation, hence False

f. Correlation just find relation between two variables which means changing position won't effect the answer. So True

g. As we need to test the difference its mean is converted to zero. So answer is True

So correct answers are b,c,f,g
