ANSWER F G H

A webpage's Design A is to be compared with Design B. The number of dicks on an
ad is counted for 15 days for each design. The measured average and standard
deviation of the daly number of cicks are given in the table below:
Design A
Design B
Average
11
18
Standard deviation
Assume the daily number of dicks is nomaily and independentdy distributed. Assume
the true variances of the daily number of cicks for both designs are equal. Use a=
0.05.
Conduct a hypothesis test to determine if the mean daily number of dicks for Design
A. MA. Is smaller than that for Design B. Ma
a. Is this a two-sided or one-sided test?
Wrte wo" or "one".
b. How many degrees of freedom are associated with the test statistic?
c. What is the pooled estimate of the common variance for both designs?
Round to 2 decimal places.
. Round to 2 decimal
d. What is the value of the test statistic?
places.
e. Find the best bounds on the Pavalue of this test using an appropriate appendix
table.
<Puvalue
. Round to 3 decimal
places.
L. Find the critical value for this test, against which the test statistic should be
compared.
Round to 3 decimal places. (Note: the sign of the
crtical value should be the same as that of the test statistic.)
g. Find the confidence bound on A - Ha to conduct this test.
Round to 2 decimal places.
h. Based on the given evidence, should you reject the null hypothesis?
Write Treject or not reject.
