D. left-tailed

2. The p-value for this test is:

A. 0.0068

B. 0.0034

C. 0.0047

D. 0.0136

3. At the 5% level, the correct conclusion is:

A. The average consumption in Santa Clara County is not 28 pounds.

B. The average consumption in Santa Clara County is less than 28 pounds.

C. The average consumption in Santa Clara County is less than 24 pounds

D.  The average consumption in Santa Clara County is 24 pounds

Write a function that plots the following trajectory equations using python turtle graphics.

x = v*sin(A)*t

y = v*cos(A)*t -.5*(9.8)*t**2

Loop through t starting at 0 and increment by .1 until y<=0. (hint, while loop) Experiment with values of velocity V (1 to 20) and angle A (0 to 90) that gives you a good plot that does not go off the screen. Position the start of the plot at the left bottom of the screen
