Q1. Perform a test of hypothesis to determine whether the average TiQ is lower than the industry standard of 2.5 minutes (150 seconds). Use a significance level of α=0.05.   I just need to know the null and alternative hypothesis for this scenario and the decision rule. Since I can't upload the file, the decision rule can just be an example with dummy numbers.
