Linear Correlation

Question

You are provided with the heights of male and female participants:
Male Female
64.00 67.00
72.00 62.00
71.00 61.00
71.00 61.00
69.00 65.00
67.00 64.00
69.00 63.00
75.00 64.00
Using the above database, compute a t-test comparing males’ and females’ heights. You must determine which type of t-test to compute. Write a short interpretation of the results.
