The average amount of time it takes for couples to further communicate with each other after their first date has ended is 3.4 days. Is this average different for blind dates? A researcher interviewed 46 couples who had recently been on blind dates and found that they averaged 3.5 days to communicate with each other after the date was over. Their standard deviation was 1.16 days. What can be concluded at the the = 0.01 level of significance?

1. For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
2. The null and alternative hypotheses would be:

H0: ? p Select an answer < = >

H1: ? p Select an answer > < =

1. The test statistic ? z t = (please show your answer to 3 decimal places.)
2. The p-value = (Please show your answer to 4 decimal places.)
3. The p-value is ? >
4. Based on this, we should Select an answer? reject fail to reject accept the null hypothesis.
