20 points pls help i’ve been staring at this question for 20 mins straight 12. Hypothesis: A sheet of cardboard that is two inches thick will block the WiFi signal from a router. Multiple thicknesses of cardboard are used, including a 0.25 inch-thick sheet, a 0.5
inch-thick sheet, a 1 inch thick sheet, a 1.5 inch-thick sheet, and a 2 inch thick sheet. Each sheet is 4 feet by 4 feet square, and the sheets are placed in the same location for each
test. A computer is used to detect the WiFi signal, and it is kept in the same location for each test. The same program is used to test the strength of the signal. Three data points are
collected for each thickness of cardboard. Would the results of this experiment be reliable? Why do you think so?
