A child psychiatrist hypothesizes that word chunking impacts language development. To investigate, the psychiatrist assesses a group of 5-year olds by asking them to recall as many words as they can starting with the letter "s". The psychiatrist then asks the parents to ensure their children practice word chunking for 20 minutes each day for three weeks. At the end of the three weeks, the psychiatrist assesses the same children by asking them to recall as many words starting with the letter "s" again. What can be concluded with an α of 0.05? The word recall data are below. 1nd 2nd 58628435 68959647 A)Obtain/compute the appropriate values to make a decision about H0. Critical Value = Test Statistic = B)If appropriate, compute the CI.
