The researcher decided to conduct the study again and selected an additional 10 children from the full time kindergarden and an additional 10 children from partime kindergarden.This time they matched the children in full time and part time based on SES, gender, age and vocabulary scores. They based their hypotheses on the finding from a previous study and wanted to see if children who attended full time kindergarden would have better short term memory recall comparred to children who attended partime kindergarden. Researcher read a list of 20 words then waited for two minutes, as the children had snacks, then ask then to tell them as many words as the could from the list of 20 words. Those who remember got a score of 1. Here is a summary of the result. full time kindergarden: 15 9 10 8 11 7 14 12 11 13 part time kindergarden: 10 7 9 8 12 6 8 10 7 9 Test the hypothses at (alpha =0.5) level of significance. Use the following 5 step procedure: step 1: state the hypothesis and identify the claim. step 2: compute the test value. step 3: compute the criical value. step 4: make the decision (reject or not reject) step 5: summarize the result. round answer to 2 decimal places.
Question(13):
The researcher decided to conduct the study again and selected an additional 10 children from the
full time kindergarden and an additional 10 children from partime kindergarden.This time they matched the children in full time and part time based on SES, gender, age and vocabulary scores.
They based their hypotheses on the finding from a previous study and wanted to see if children
who attended full time kindergarden would have better short term memory recall comparred to
children who attended partime kindergarden. Researcher read a list of 20 words then waited for
two minutes, as the children had snacks, then ask then to tell them as many words as the could
from the list of 20 words. Those who remember got a score of 1. Here is a summary of the result.
full time kindergarden: 15 9 10 8 11 7 14 12 11 13
part time kindergarden: 10 7 9 8 12 6 8 10 7 9
Test the hypothses at (alpha =0.5) level of significance.
Use the following 5 step procedure:
step 1: state the hypothesis and identify the claim.
step 2: compute the test value.
step 3: compute the criical value.
step 4: make the decision (reject or not reject)
step 5: summarize the result.
round answer to 2 decimal places.
