Question
The average amount of time it takes for couples to further communicate with each other after their first date
has ended is 3.77 days. Is this average different for blind dates? A researcher interviewed 61 couples who had
recently been on blind dates and found that they averaged 3.9 days to communicate with each other after the
date was over. Their standard deviation was 1.477 days. What can be concluded at 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:
Select an answer O
H1:
Select an answer
c. The test statistic ? O -
(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 > 8 a
f. Based on this, we should accept
g. Thus, the final conclusion is that ...
e the null hypothesis.
The data suggest that the population mean is not significantly different from 3.77 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 different
from 3.77.
The data suggest the populaton mean is significantly different from 3.77 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 different from
3.77.
O The data suggest the population mean is not significantly different from 3.77 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
3.77.
