(Please show your answer to 4 decimal places.)
O The data suggest the population mean is not significantly different from 3.03 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 3.03.
O The data suggest the populaton mean is significantly different from 3.03 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 different
from 3.03.
O The data suggest that the population mean is not significantly different from 3.03 at a = 0.10,
so there is statistically insignificant evidence to conclude that the population mean time for
couples who have been or blind date communicate with each other after the date is over
is different from 3.03.

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 different for blind dates? A researcher interviewed 55 couples
who had recently been on blind dates and found that they averaged 2.7 days to communicate with each
other after the date was over. Their standard deviation was 0.943 days. What can be concluded at the a =
0.10 level of significance?
a. For this study, we should use z-test for a population proportion
b. The null and alternative hypotheses would be:
Ho: Uv

H₁: #
