A random sample of 900 13- to 17-year-olds found that 411 had a computer in their room with Internet access. Let p be the proportion of all teens in this age range who have a computer in their room with Internet access. Suppose you wished to see if the majority of teens in this age range have a computer in their room with Internet access. To do this, you test the hypotheses H0: p = 0.50 vs HA : p≠0.50
The test statistic for this test is:.
a. 1.96
b. 2.60
c. 27.50
d. 2.59424
