researchers were interested in the mean number of words recalled from short term memory differs based on if children attended full time kindergarden or part time kinder garden. Researchers randomly select 7 students from full time kinder garden and 9 from part time kinder garden.Researchers read a list 0f 20 words, then waited for two minutes while the children were having snacks. THey were then asked to tell how many words they remember. Those that can remember a word correctly got a score of 1. Here is a summary of the result: full time kindergarden: 14 17 12 16 15 12 13 part time kindergarden: 5 6 7 8 9 10 11 5 6 test the hypotheses at(alpha =.05) level of significance use the following 5 step procedure step1: state the null hypotheses and idenitfy the claim. step2 :compute the test value step3: compute the critical value step4: make the decision(reject or not rejeci) step 5: summarize the result.

part time kindergarden: 5 6 7 8 9 10 11 5 6
test the hypotheses at(alpha =.05) level of significance
use the following 5 step procedure
step1: state the null hypotheses and idenitfy the claim.
step2 :compute the test value
step3: compute the critical value
step4: make the decision(reject or not rejeci)
step 5: summarize the result.
