The average amount of time it takes for couples to further communicate with each other after their first date has ended is 3.1 days with a standard deviation of 1.8 days. Is this average different for blind dates? A researcher interviewed 32 couples who had recently been on blind dates and found that they averaged 4 days to communicate with each other after the date was over. What can be concluded at the 10% level of significance? What are the correct hypotheses? Ho: " 3.1 H₁: μ Based on the hypotheses, find the following: Test Statistic z = 2.8482 Critical Values = 1.645 3.1 days days x (Round to 4 decimal places.) x (Round to 2 decimal places.) Based on the above we choose to Reject the null hypothesis The correct summary would be: There is enough evidence to reject the claim amount of time to communicate after a blind date is different than 3.1. X that the average
