Question

Expedia would like to test if the average round-trip airfare between Philadelphia and Dublin is less than $1,200. The correct hypothesis statement would be ________. A) H₀: μ ≠ $1,200, H_A: μ = $1,200 B) H₀: μ < $1,200, H_A: μ ≥ $1,200 C) H₀: μ ≥ $1,200, H_A: μ < $1,200 D) H₀: μ = $1,200, H_A: μ ≠ $1,200

The null hypothesis (H₀) should state that the average round-trip airfare is greater than or equal to $1,200, while the alternative hypothesis (H_A) should state that the average round-trip airfare is less than $1,200. Therefore, choice (C) correctly states the hypotheses.
