Therefore, I would be comfortable in assuming that the sample came from a normal distribution. b. Yes, since most of the observations do form a linear function, I would be comfortable in assuming that the sample came from a normal distribution. This is without regard to the few outliers that occur within the QQ plot. c. This test resulted in a p -value of 0.8529. Since this is larger than = 0.05, we fail to α reject the null hypothesis that the sample came from a normal distribution. d. This test resulted in a p -value that is larger than 0.15. Since this is already larger than = α 0.05, we fail to reject the null hypothesis that the sample came from a normal distribution. e. This test resulted in a p -value that is larger than 0.25. Since this is already larger than = α 0.05, we fail to reject the null hypothesis that the sample came from a normal distribution. f. This test resulted in a p -value that is larger than 0.25. Since this is already larger than = α 0.05, we fail to reject the null hypothesis that the sample came from a normal distribution.
