Identify which of the following are valid statements Circle

Identify which of the following are valid statements. Circle T or F. T F Bar charts are used to display categorical data. T F The principle of least squares states that the best line minimizes the sum of residuals. T F Population standard deviation is the same as sample standard deviation. T F For any two event A and B. P(A\\B) LT P(A). T F Mean does not get affected by extreme observations. T F Residual plot examines linearity and constant variability of a linear regression model. T F A right skewed distribution has a heavy tail on the right. T F Mutually exclusive events should be independent as well. T F For any two events A and B. P(A n B) = P)(A)-P{B) T F The range of a data set is always greater than or equal to the IQR of the same data set
