Question

Researchers wanted to see if a certain image in ads affected​ people's ability to remember the item being advertised. They found two ads for each of 10 similar​ items, one with the image and one without. Then they showed the ads to 10 randomly selected people for one minute and asked them to list as many of the items as they could. The results for the number of items remembered are shown in the table below. Is there evidence that the image​ mattered? Use α equals=0.05

Subject	1	2	3	4	5	6	7	8	9	10
Image	3	2	4	4	3	6	2	1	4	2
No image	3	1	5	4	2	6	0	3	6	3

Compute the test statistic. Use No image −Image as the difference.

The test statistic is

nothing .

​(Round to two decimal places as​ needed.)

Find the​ P-value.

The​ P-value is

nothing .

​(Round to four decimal places as​ needed.)

There is insufficient

or

There is

evidence that the image has an effect on the ability of people to remember the item being advertised because the​ P-value of the appropriate hypothesis test is

▼

large

or

small

Answer 1

from above:

test statistic =0.48

p value =0.6424 (please try 0.3212 if this comes wrong)

There is insufficient evidence that the image has an effect on the ability of people to remember the item being advertised because the​ P-value of the appropriate hypothesis test is larger
