Light enters a solid tube made of plastic having an index of refraction of 1.60. The light travels parallel to the upper part of the tube. You want to cut the face AB so that all the light will reflect back onto the tube after it first strikes that face.
(a) what is the largest that Theta can be if the tube is in air?
(b) if the tube is immersed in water of refractive index 1.33, what is the largest that Theta can be?

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
