We're interested in whether there's a relationship between the Visual and ReadWrite learning styles of Biology students. We know that the standard deviation of Visual scores for the students in our classroom is 3.231746, the standard deviation for the ReadWrite scores is 3.578245, and the covariance between these two variables is 3.747628. Calculate the Pearson product-moment correlation coefficient for these two variables, based on these numbers:

0.3241

Question 36 Calculate the t-statistic associated with the null hypothesis that there is no correlation between the VARK Visual and VARK ReadWrite scores:

Need help on 36,

Number of students is 269
