Researchers were interested in whether the mean number of words recalled from short term memory differ based on children attending full time day care or part time daycare.Researchers randomly selected 7 children from full time day care and 9 from partime daycare. Researchers read from a list of 20 words, then waited for 2 minutes while the children were having a snack, then there asked to tell how many words they remember. Those that gave a correct answer get score of 1. A summary of the result is given below full time kinder garden: 14 17 12 16 15 12 13 part time kinder garden: 5 6 7 8 9 10 11 5 6 test the hypotheses(alpha =.05) level of signifance and the following five step procedure. step 1: state the null hypothese and idenifty the claim step2: compute the test value step 3: compute the critical value step 4: make the decision(reject or not reject) step 5: summarize the results round answer to 2 decimal places
