CAN SOMEBODY HELP ME WITH THIS QUESTIONSSSS?

Question 2 Consider a pair of datasets, x and y. Which of the following is the best description of the covariance of the two datasets: O The covariance describes how much the two variables, x and y. change together. O The covariance describes the spread of the variable x about the mean of the variabley The covariance describes the gradient of the line of best fit on the scatter plot of y versus x. O The covariance describes the gradient of the line of best fit on the scatter plot of x versus y Question 5 Which one of the following statements is false: it is never acceptable to make decisions on which data points to remove from an experimental result, as this is an example of falsifying data. O Data is sometimes entered incorrectly, so it is reasonable to remove these data points from an experimental result. O It is reasonable to make decisions on which data points to remove from an experimental result, as long as any such deletions are declared O Sometimes a significant outlier can affect accurate statistical characterisation, so it is reasonable to remove these outliers to determine their impact
