Hi professor
I am having trouble finding the t-value on #14 of section 9.3. The df is 52, however, I don't see 52 on the t-table chart.

Hi Shirley,

When your degrees of freedom are between two values on the table, I recommend that you choose the nearest degrees of freedom that is less than the one you are trying to find. For example, if you are looking for 52 degrees of freedom which is not on the table, the closest value that is less than 52 is 50.  

Watch the video below from the 7:30 minute mark until the 8:40 minute mark. 

Hope that helps,

Professor McGuckian
