Which of the following statements are TRUE: (a) If the there is a strong linear correlation between two bivariate variables then there is a cause and affect between these two bivariate variables (b) If the ordered pairs (Height, Weight) of a scatterplot are interchanged to the ordered pairs (Weight, Height) then the value of the Correlation Coefficient of the bivariate variables, Height and Weight, will not change (c) If all the points of a scatterplot are aligned perfectly on a horizontal line then there is a strong correlation between the bivariate variables that this scatterplot represents (d) The Alternative Hypothesis represents what you really want to happen (e) When doing a Hypothesis Test the Critical Zscore value(s) depends on both the value of the specified Significance Level and the relational operator use in the Alternative Hypothesis (f) If two bivariate variables have a Correlation Coefficient equal to -0.9828 then there is a weak correlation between these two bivariate variables
Which of the following statements are TRUE:

(c) If all the points of a scatterplot are aligned perfectly on a horizontal line then there is a strong correlation between the bivariate variables that this scatterplot represents
(d) The Alternative Hypothesis represents what you really want to happen
(e) When doing a Hypothesis Test the Critical Zscore value(s) depends on both the value of the specified Significance Level and the relational operator use in the Alternative Hypothesis
(f) If two bivariate variables have a Correlation Coefficient equal to -0.9828 then there is a weak correlation between these two bivariate variables
