Question: If the correlation coefficient is negative, this means the calculation was done wrong the regression line can be used for prediction the test statistic, t,

If the correlation coefficient is negative, this means

  • the calculation was done wrong
  • the regression line can be used for prediction
  • the test statistic, t, can not be calculated
  • the slope of the regression line is negative
  • there is a strong correlation between the variables
  • there is no correlation between the variables
