A random sample of 100 likely voters in a small city produced 59 voters in favor of Candidate A. The observed value of the test statistic for testing the null hypothesis H0 : p = 0.5 versus the alternative hypothesis Ha : p > 0.5 is
(a) z =
0.59 − 0.5
Å
0.59(0.41)
100
(d) z =
0.5 − 0.59
Å
0.5(0.5)
100
(b) z =
0.59 − 0.5
Å
0.5(0.5)
100
(e) t =
0.59 − 0.5
Å
0.5(0.5)
100
(c) z =
0.5 − 0.59
Å
0.59(0.41)
