| johntan1979 | Type II error... no conclusive evidence. |
| johntan1979 | Also, failing to reject null is not the same as accepting null. |
| lndcobra | In the question H_0 is μ < 931, and they fail to reject it, so C is also incorrect, as it could mean that hospital costs equal to 931 (μ = 931) |
| wpaxtonn21 | @johntan1979 this is not a type II error. |
