The average amount of time it takes for couples to further communicate with each other after their first date has ended is 2.59 days. Is this average shorter for blind dates?

Question

The average amount of time it takes for couples to further communicate with each other after their first date has ended is 2.59 days. Is this average shorter for blind dates? A researcher interviewed 62 couples who had recently been on blind dates and found that they averaged 2.5 days to communicate with each other after the date was over. Their standard deviation was 0.899 days. What can be concluded at the the αα = 0.10 level of significance?

For this study, we should use
The null and alternative hypotheses would be:

H0:H0:

H1:H1:

The test statistic = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is αα
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest that the population mean is not significantly less than 2.59 at αα = 0.10, so there is statistically insignificant evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is less than 2.59.
- The data suggest the population mean is not significantly less than 2.59 at αα = 0.10, so there is statistically significant evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is equal to 2.59.
- The data suggest the populaton mean is significantly less than 2.59 at αα = 0.10, so there is statistically significant evidence to conclude that the population mean time for couples who have been on a blind date to communicate with each other after the date is over is less than 2.59.
