One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows. 4; 7; −1; 1; 0; 5; −2; 2; −1; 6; 5; −3 Part (a) What is the mean change score? (Round your answer to two decimal places.)

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.

Autopitch devices are made for both major- and minor-league teams to help them improve their batting averages. When set at the standard position, Autopitch can throw hardballs toward a batter at an average speed of 53 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 9 devices at a time. The average range is 4 mph. a) Using this information, construct control limits for the x-chart. UCL,-mph (round your response to three decimal places).
