HOTSPOT LABEL The times (in seconds) of 8 runners for the 100-yard dash are recorded and used to determine the following calculations. Mean: 11.8 Median: 12.2 CO Mode: 12.5 Range: 3.2 The timekeeper had difficulties with the stopwatch and did not start the time until the runners had been running for 1.5 seconds. What would these calcula- tions be if this 1.5 seconds were added to each runner's 100-yard dash time? . Press each hotspot.

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Autism) if a researcher would like to determine if there is a significant difference between "Autistic," "Normal," and "Mentally Retarded"? The researcher took measurements of the serum concentration of an antigen in three groups of children (Autistic, Normal, and Mentally Retarded). Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on "Autism"? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the serum concentration of antigen between "Autistic," "Normal," and "Mentally Retarded"? 2. What is the computed Mean of "Mentally Retarded" on the given data for Autism? Round it off to two decimal places. 3. What is the computed Standard Deviation of the "Autistic" group on the given data for Autism? Round it off to two decimal places.
