Question
You are tasked with testing the following claim (\( H_a \)) at a significance level of \( \alpha = 0.10 \): - \( H_0: \mu = 65.4 \) - \( H_a: \mu \neq 65.4 \) The population is assumed to be normally distributed, but the standard deviation is unknown. The sample data collected includes the values: - 61.9 - 13 - 43.5 - 34.1 **Questions to Answer:** 1. **What is the test statistic for this sample? (Report the answer accurate to three decimal places.)** - Test statistic = [Input required] 2. **What is the p-value for this sample? (Report the answer accurate to four decimal places.)** - p-value = [Input required] 3. **Determine the p-value condition:** - Is the p-value less than (or equal to) \( \alpha \)? - Is the p-value greater than \( \alpha \)? 4. **Decision Based on Test Statistic:** - Choose to reject the null hypothesis - Choose to accept the null hypothesis
