question(13):

The researcher decided to conduct the study again and recruited an  additional 10 children  from the

full time kindergarden and an additional from the part time kindergarden, This time they matched the

children in full time kindergarden and partime kindergarden on SES, gender, age, and vocabulary

score .They based their hypotheses  on the finding from a previous study  and wanted to see if

full time kinder garden  would have better short term memory recall compared to children who attended partime kindergarden. Researchers read a list of 20 words ,then waited 2 minrderdenutes while

the kids were having a snack, then they were asked to tell them how many words they remember.

.Those who remember a word got a score of 1. A summary of the results is given below

fulltime kindergarden: 15     9      10      8         11      7         14        12     11   13

partime kindergarden :  10   7      9      8         12       6         8          10      7      9

test the hypotheses at (alpha =.05) level of significance.

Use the 5 step procedure

Step 1:   state the hypothesis and identify the claim

Step 2 : compute the test value

Step 3: compute the critical value.

Step4:  Make the decision(reject or not reject)

Step 5: summarize the results

round your answer to 2 decimal places.
