In 2015, people all over the internet were hotly debating whether a specific dress was actually white and gold (WG) or black and blue (BB). The photograph was unusually lit and provided little context beyond the dress itself, leaving much to interpretation. The dress therefore made an excellent tool to study the involvement of higher cognitive functions in color perception. Researchers recruited a random sample of adults, some of whom perceived the dress to be WG and some of whom perceived it to be BB. While the subjects were looking at the picture of the dress on a computer screen, their relative brain activity in the frontal cortex was assessed using functional magnetic resonance imaging (fMRI) brain imaging. The table contains the findings. Macmillan Learning SOLVE: Calculate the test statistic. Test the difference between μBB and HwG. Give your answer to two decimal places. = Give an inequality statement about the P-value. 0.001 < P < 0.01
