a researcher wants to assemble a bike. She does not know which set of instructions is better for helping her to put together the bike quickly. To find out which set of instructions is better, she decides to conduct a study. She finds eight people, Half of the people are given one set of instructions and the other half of the people are given the second set of instructions. Each person gets an unassembled bike. She measures how much time is needed for each person to assemble the bike using the instructions that she gives them. Thus, the scores below in the table are the number of minutes i took to assemble the bike. Instruction Set 1: 15,22,28,14 M=19.75 and SD 6.55. Instructions Set 2: 14, 10, 12,8 M=11 and SD 2.58. Calculate the t test? Do I need to calculate pooled variance for this
