Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver's head during a crash test is equal for each types of car. Use a = 5%. Use Excel to perform the analysis. What is the F critical value up to two decimal points? Compact cars Midsize cars Full-size cars 643 469 484 655 427 456 702 525 402 Answer:

Time left 0:56:37 P Flag question The table shows lifetimes under controlled conditions, in hours in excess of 1000 hours, of samples of 60W electric light bulbs of three different brands. Brand 2 3 16 18 26 15 22 31 13 20 24 21 16 30 15 24 24 Assuming all lifetimes to be normally distributed with common variances, test at 1% level of significance, the hypothesis that there is no difference between the three brands with respect to mean lifetime. What is F critical value up to two decimal points? Answer:
