Hey, since there are multiple subparts posted, we will answer first three question. If you want any…

O The data suggest that the population mean is not significantly less than 3 at a - 0.01, 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 3. O The data suggest the population mean is not significantly less than 3 at a = 0.01, 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. O The data suggest the populaton mean is significantly less than 3 at a - 0.01, 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 3.

Question

Syricing
The average amount of time it takes for couples to further communicate with each other after their first
date has ended is 3 days. Is this average shorter for blind dates? A researcher interviewed 58 couples who
had recently been on blind dates and found that they averaged 2.8 days to communicate with each other
after the date was over. Their standard deviation was 0.7 days. What can be concluded at the the a = 0.01
level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: ?v Select an answer v
H: ?vSelect an answer 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 a
f. Based on this, we should Select an answer v the null hypothesis.
Thus, the final conclusion is that ...
O The data suggest that the population mean is not significantly less than 3 at a = 0.01, 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 3.
O The data suggest the population mean is not significantly less than 3 at a 0.01, 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.
O The data suggest the populaton mean is significantly less than 3 at - 0.01, 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 3.
