The average amount of time it takes for couples to further communicate with each other after their first date has ended is 2.5 days with a standard deviation of 1.8 days. Is this average different for blind dates? A researcher interviewed 35 couples who had recently been on blind dates and found that they averaged 3.6 days to communicate with each other after the date was over. What can be concluded at the 5% level of significance? What are the correct hypotheses? Ho: Select an answer ▼ days Hj: Select an answer v days Based on the hypotheses, find the following: Test Statistic z = (Round to 4 decimal places.) Critical Values = (Round to 2 decimal places.) Based on the above we choose to Select an answer The correct summary would be: Select an answer v that the average amount of time to communicate after a blind date is different than 2.5.
