Explain how the equation of the line of symmetry relates to the equation of an absolute value function
f(x) = lr - a +b.
c.
a. the equation for the line of symmetry is
x= -a. the line of symmetry occurs
when x equals -a.
the equation for the line of symmetry is
r = b. the line of symmetry occurs when
x equals -b.
d.
the equation for the line of symmetry is
x = a. the line of symmetry occurs when
x equals a.
the equation for the line of symmetry is
x = b. the line of symmetry occurs when
x equals b.

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?
