A study investigates whether the color of text affects memory recall. Two groups of participants (n=40 each) are asked to remember words from a list. One group sees the words in black text, while the other sees them in blue text. After a 30-minute interval, they are asked to recall as many words as possible. The number of words recalled is recorded, with higher numbers indicating better recall. The researcher wants to determine if text color influences memory recall.

The dataset can be found on Blackboard. Using the 4-step hypothesis testing, what should this researcher conclude? Make sure to show work and go though all 4 steps.
