A local Asian restaurant claims that they complete orders in under 30 minutes, on average. However, it always seems to take longer when you order food from them. To investigate their claim, you randomly select 20 different times during the next month to visit the restaurant. The 99% confidence interval for the mean
order completion time is 25.3 minutes to 42.6 minutes.
Based on the confidence interval, is it plausible that the true average order completion time is less than 30 minutes? Explain.
O No, because our interval includes sometimes that are more than 30
Yes, because our interval includes some times that are less than 30
O Yes, because our interval includes some times that are more than 30
O No, because our interval includes sometimes that are less than 30
