Column Formula CI Calculating

Aug 7, 2023 10:01 AM (678 views)

I'm putting CI into columns and need to calculate the t-statistic from a look up table that will vary row to row. How do I use a formula to write the value for,

t(0.05,(n1+n2-2)

value from a t-table at 2-sided 90% CI (0.05), and degrees of freedom
