Ho: ? ?v
H1: ? v?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.
g. Thus, the final conclusion is that ...
O The data suggest that the population mean final exam score for students who are given colored pens
at the beginning of class is not significantly higher than 74 at a = 0.01, so there is statistically
insignificant evidence to conclude that the population mean final exam score for students who are
given colored pens at the beginning of class is higher than 74.
O The data suggest the populaton mean is significantly higher than 74 at a = 0.01, so there is
statistically significant evidence to conclude that the population mean final exam score for students
who are given colored pens at the beginning of class is higher than 74,
O The data suggest the population mean is not significantly higher than 74 at a= 0.01, so there is
statistically insignificant evidence to conclude that the population mean final exam score for
students who are given colorcd pens at the beginning of class is equal to 74.
