Gavin was playing with a spinner that has 4 equal areas, numbered 1, 2, 3 and 4.
Gavin
spun the spinner 100 times and 26 of the 100 spins came up as a 4. He wanted
to see how likely a result of 26 fours in 100 spins would be with a fair spinner, so
Gavin used a computer simulation to see the proportion of fours in 100 spins,
repeated 100 times, assuming a probability of of spinning a 4. Create a 95%
confidence interval based on the data from the simulation, to the nearest hundredth,
and state whether the observed proportion of fours is within the margin of error of
the simulation results.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
