Before the furniture store began its ad campaign, it averaged 130 customers per day. The manager is
investigating if the average is smaller since the ad came out. The data for the 16 randomly selected days
since the ad campaign began is shown below:
109, 117, 133, 117, 134, 129, 110, 136, 110, 128, 113, 138, 125, 99, 145, 114
Assuming that the distribution is normal, what can be concluded at the a = 0.10 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Но:
? v
Select an answer v
H1: ? v
Select an answer v
c. The test statistic
(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 number of customers since the ad campaign began
is not significantly less than 130 at a = 0.10, so there is insufficient evidence to conclude that
the population mean number of customers since the ad campaign began is less than 130.
O The data suggest the populaton mean is significantly less than 130 at a = 0.10, so there is
sufficient evidence to conclude that the population mean number of customers since the ad
campaign began is less than 130.
O The data suggest the population mean is not significantly less than 130 at a = 0.10, so there is
sufficient evidence to conctude that the population mean number of customers since the ad
campaign began is equal to 130.
