The average amount of time it takes for couples to further communicate with each other after their first date has ended is 3.03 days. Is this average longer for blind dates? A researcher interviewed 61 couples who had recently been on blind dates and found that they averaged 3.4 days to communicate with each other after the date was over. Their standard deviation was 1.063 days. What can be concluded at the the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: H1: ? v c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest that the population mean is not significantly greater than 3.03 at a = 0.05, 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 greater than 3.03. 0.05, so there is statistically The data suggest the populaton mean is significantly greater than 3.03 at a = 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 greater than 3.03. The data suggest the population mean is not significantly greater than 3.03 at a = 0.05, 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 3.03.

Question
Transcribed Image Text:The average amount of time it takes for couples to further communicate with each other after their first date has ended is
3.03 days. Is this average longer for blind dates? A researcher interviewed 61 couples who had recently been on blind
dates and found that they averaged 3.4 days to communicate with each other after the date was over. Their standard
deviation was 1.063 days. What can be concluded at the the a = 0.05 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Но:
H1:
? v
c. The test statistic ? v
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? v
f. Based on this, we should Select an answer the null hypothesis.
g. Thus, the final conclusion is that ...
The data suggest that the population mean is not significantly greater than 3.03 at a = 0.05, 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 greater than 3.03.
0.05, so there is statistically
The data suggest the populaton mean is significantly greater than 3.03 at a =
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 greater than 3.03.
The data suggest the population mean is not significantly greater than 3.03 at a = 0.05, 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 3.03.
