The average amount of time it takes for couples to further communicate with each other after their flrst
date has ended is 2.35 days. Is this average different for blind dates? A researcher interviewed 70 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 0.655 days. What can be concluded at the the
a = 0.10 level of significance?
a. For this study, we should use Select an answer
b. The null and alternatíve hypotheses would be:
Ho: ?vSelect an answerv
H: ?vSelect an answerv
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 answerv the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest that the population mean is not significantly different from 2.35 at a = 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 different from 2.35.
O The data suggest the population mean is not significantly different from 2.35 at a = 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 2.35.
O The data suggest the populaton mean is signtficantly different from 2.35 at a = 0.10, so there
is statistically significant evidence to conclude that the population mean time for couples who
have been on a blínd date to communicate with each other after the date is over is different
from 2.35.
