Pythagorean identities: sin?(8)+ cos2(0) = 1
Which statement(s) are true based on the
Pythagorean identities?
sin? 8 = 1+cos e
tan?(0)+1= sec?(0)
1 = sec28-tan?
1 + cot? (0) = csc?(0)
cot?e=csc26-1
1-tan? 6 --sec?
-cos= sin? 8-1

The vice president of programming at nbc is finalizing the prime-time schedule for the fall. she has decided to include a hospital drama but is unsure which of two possibilities to select. she has a pilot called the surgeon and another called critical care. to her make a final decision, a sample of 20 viewers from throughout the united states was asked to watch the two pilots and indicate which show they prefer. the results were that 12 liked the surgeon, 7 liked critical care, and one had no preference. state the decision rule, using the 0.10 significance level. h0: π = 0.50 h1: π ≠ 0.50 1. reject h0 if number of + signs is either < = or > = 2. what is your decision regarding h0? is there a preference for one of the two shows?
