A projectile, fired with unknown initial velocity, lands [t] s later on the side of a hill, [x] km away and [y] m vertically above the starting point. What is the magnitude of the initial velocity?

The step of squaring deviations when computing the standard deviation is done to

In a long range shooting competition on the television series Top Shot, a bullet is fired at 25.2° above the horizontal with a muzzle velocity of [v0] m/s. The bullet strikes a target on a hill that is [dist] km horizontally from the shooter. How far vertically above the shooter is the target located? (In other words, how tall is the hill?)

A certain experimental vehicle needs to accelerate from rest to [v] m/s in a distance of [x] m. What total time is needed for the vehicle to reach its final speed?

When computing standard deviation, what does it mean if a person computes a SD value of -2?

A store supervisor codes each of her employees in terms of how often they show up on time for their shifts: 1=at least 95% of their shifts, 2=between 80% and 94% of their shifts, 3=between 50% and 79% of their shifts, and 4=less than 50% of their shifts.  What measurement scale is this 1-4 coding scheme?

I attest that the work submitted here is my own and that I have not used any class notes or outside resources to assist me in completing this exam.  After submission, I will upload any scratch paper that I used during the exam.

(P2-3) In one or two sentences, describe to this manager what the mean and standard deviation you calculated in the previous items can tell her about what she should expect among all of her warehouse employees regarding lateness to work. [4 pts]

 (P1-1) What is the researcher’s hypothesis? [3 pts]
