All the other answers are wrong b. 6.507 is between .484 and 11.143 so we fail to reject a standard deviation of 20. There is nothing wrong with the analysis c. 6.507 is between .831 and 12.832 so we falil to reject a standard deviation of 20. However, the sample is not random because the highest numbers have been selectee d. 6.507 is between .484 and 11.143 so we falil to reject a standard deviation of 20. However, the sample is no random because the highest numbers have been selected
