Question

A sample of 16 ATM transactions shows a mean transaction time of 67 seconds with a standard deviation of 12 seconds. State the hypotheses to test whether the mean transaction time exceeds 60 seconds. A)H₀: μ ≤ 60, H₁: μ > 60 B)H₀: μ ≥ 60, H₁: μ < 60 C)H₀: μ = 60, H₁: μ ≠ 60 D)H₀: μ < 60, H₁: μ ≥ 60

The null hypothesis (H0) is that the mean transaction time does not exceed 60 seconds (μ ≤ 60), and the alternative hypothesis (H1) is that the mean transaction time exceeds 60 seconds (μ > 60). This setup is used to test if the mean time is greater than a specified value.
