- Claim: μ = 40
- α = 0.05
- σ = 3.62
- Sample statistics: x̄ = 39.7, n = 70

**The standardized test statistic is:**

  - (Round to two decimal places as needed.)

**Determine the critical value(s). Select the correct choice below and fill in the answer box to complete your choice.**
  - (Round to two decimal places as needed.)

- A. The critical values are ± 1.96.
- B. The critical value is: (options not fully visible).

**Determine the outcome and conclusion of the test. Choose the correct answer below.**

- A. Fail to reject H₀. At the 5% significance level, there is not enough evidence to support the claim.
