answer part 3

Suppose you perform the hypothesis test \( H_0: \mu = 90 \) versus \( H_1: \mu > 90 \). The population variance, \( \sigma^2 \), is unknown. The sample size is \( n = 6 \). Assume the significance level is 0.01. **Part 1:** 1) Should you use \( z \) or \( t \) to find the critical value? - \( z \) - \(\mathbf{t} \) (selected) **Part 2:** 2) Choose the correct critical region. - Reject \( H_0 \) if \( t > t_{\alpha} \) - Reject \( H_0 \) if \( t \geq t_{\alpha} \) - \(\mathbf{Reject \ H_0 \ if \ t > t_{\frac{\alpha}{2}} }\) (selected) - Reject \( H_0 \) if \( t \geq t_{\frac{\alpha}{2}} \) - Reject \( H_0 \) if \( t < -t_{\alpha} \) - Reject \( H_0 \) if \( t \leq -t_{\alpha} \) - Reject \( H_0 \) if \( t < -t_{\frac{\alpha}{2}} \) - Reject \( H_0 \) if \( t \leq -t_{\frac{\alpha}{2}} \) - Reject \( H_0 \) if \( t < -t_{\alpha} \) or \( t > t_{\alpha} \) - Reject \( H_0 \) if \( t \leq -t_{\alpha} \) or \( t \geq t_{\alpha} \) - Reject \( H_0 \) if \( t < -t_{\frac{\alpha}{2}} \) or \( t > t_{\frac{\alpha}{2}} \) - Reject \( H_0 \) if \( t \leq -t_{\frac{\alpha}{2}} \) or \( t \geq t_{\frac{\alpha}{2}} \) **Part 3:** 3) Identify the critical value. If there are multiple critical values, separate them using commas. If using \( z \), round to 2 decimals; if using \( t \), round to 3 decimals. \[ \text{(Input Box)} \
