The average 5 year old can read 17 words per minute, with a standard deviation of 3. We gathered a sample of 81 "gifted" 5 year olds and they read an average of 22 words per minute. When alpha is set at 0.05, calculate a one sample z test to determine if the gifted 5 year olds read at a different pace than the average 5 year old population. Step 1: State the hypotheses Step 2: Set the criteria Step 3: Calculate the test statistic Step 4: Make a decision Calculate Cohen's d
