A consumer magazine wants to figure out which of two major airlines lost a higher proportion of luggage on international flights. The magazine surveyed Standard Air (population 1) and Down Under airlines (population 2). Standard Air lost 45 out of 600 bags. Down Under airlines lost 30 of 500 bags. Does Standard Air have a higher population proportion of lost bags on international flights? Which of the following is the correct competing hypotheses? A) H 0 : p = p 0 , H A : p ≠ p 0 B) H 0 : p 1 - p 2 = 0, H A : p 1 - p 2 ≠ 0 C) H 0 : p 1 - p 2 ≤ 0, H A : p 1 - p 2 0 D) H 0 : p 1 - p 2 ≥ 0, H A : p 1 - p 2

Does Standard Air have a higher population proportion of lost bags on international flights? Which of the following is the correct competing hypotheses?
A) H 0 : p = p 0 , H A : p ≠ p 0 
B) H 0 : p 1 - p 2 = 0, H A : p 1 - p 2 ≠ 0
C) H 0 : p 1 - p 2 ≤ 0, H A : p 1 - p 2 > 0
D) H 0 : p 1 - p 2 ≥ 0, H A : p 1 - p 2 < 0

Quizplus · Accepted Answer

The correct competing hypotheses to determine if Standard Air has a higher population proportion of lost bags than Down Under airlines are: Null hypothesis (H0) stating that the proportion of lost bags for Standard Air is less than or equal to that of Down Under airlines, and the alternative hypothesis (Ha) stating that the proportion of lost bags for Standard Air is greater than that of Down Under airlines.
