Question

Sleep researchers theorize that 25% of the general population suffers from obstructive sleep apnea. Researchers found that 124 of 159 emergency room nurses suffered from obstructive sleep apnea. -The appropriate hypotheses that attempt to provide that emergency room nurses differ from the general population proportion is _____. A)H₀: p ≤ .780 vs H_A: p > .780 B)H₀: p ≥ .250 vs H_A: p < .250 C)H₀: p ≤ .250 vs H_A: p > .250 D)H₀: p = .250 vs H_A: p ≠ .250 E)H₀: p ≠ .250 vs H_A: p = .250

Quizplus · Accepted Answer

The null hypothesis (H0) should state that the proportion of emergency room nurses with sleep apnea is equal to the general population proportion (0.250), and the alternative hypothesis (HA) should state that it is different, indicating a two-tailed test.
