The local airport authority wants to investigate whether the mean of handled passengers per month has increased from 64,500 to plan maintenance works. Determine the valid null and alternative hypotheses. A) H₀: 64,500 versus Ha: = 64,500 B) H₀: µ = 64,500 versus Ha: µ 64,500 C) H₀: = 64,500 versus Ha: µ 64,500 D) H₀: µ 64,500 versus Ha: µ = 64,500 E) H₀: = 64,500 versus Ha: 64,500

Question

The local airport authority wants to investigate whether the mean of handled passengers per month has increased from 64,500 to plan maintenance works. Determine the valid null and alternative hypotheses. A) H₀: > 64,500 versus Ha: = 64,500 B) H₀: µ = 64,500 versus Ha: µ > 64,500 C) H₀: = 64,500 versus Ha: µ > 64,500 D) H₀: µ > 64,500 versus Ha: µ = 64,500 E) H₀: = 64,500 versus Ha: > 64,500

The null hypothesis should state that there is no difference or no change in the mean number of handled passengers per month, which is µ = 64,500. The alternative hypothesis should state that there is an increase in the mean number of handled passengers per month, which is represented by µ > 64,500. Therefore, option B is the valid null and alternative hypotheses. Option A, C, D, and E are invalid because they either have incorrect symbols or do not represent the correct hypotheses.
