JUST ANSWER QUESTION 6, PLEASE

Based on the following data for car crash deceleration measurements, do an ANOVA test and answer question 5 (i.e., the question that will be #5 on the test)

Small cars: 45, 43, 44, 54, 38, 43, 42, 45, 44, 50
Medium cars: 30, 49, 43, 41, 47, 42, 37, 43, 44, 34
Large cars: 30, 37, 38, 45, 37, 33, 38, 45, 43, 42

5. What is the test statistic of F for this data? The Critical Value of F?Based on the following data for car crash deceleration measurements, do a 2-Way ANOVA test and determine if car size and /or country of origin make a difference in crash effects on the passenger. Use results to answer question 6 (i.e., the question that will be #6 on the test)
