You are conducting a significance test of h0: μ = 5 against ha: μ > 5. after checking the conditions are met from a simple random sample of 30 observations, you obtain t = 2.35. based on this result, describe the p-value. the p-value falls between 0.15 and 0.2. the p-value falls between 0.025 and 0.05. the p-value falls between 0.01 and 0.02. the p-value falls between 0.005 and 0.01. the p-value is less than 0.005.
