Using the artofstat website, run a permutation test to see if there is a difference in the mean amount of time spent on emails per day between in state and out of state students. (make sure to generate 10,000 permutations.) in state students: 2 3 3 6 2 1 1 5 3 2.5 out of state students: 1 2 2 1 2 1 4 3 9 1 10 1 3 what is the p-value?

Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.
