The accompanying observations (shown in Table 2) are about residual flame time (sec) for strips of treated children's nightwear. Suppose a true average flame time of at most 9.8 had been mandated. Does the data suggest that this condi- tion has not been met? Assuming normality assumption of such data, answer the following questions. Table 2: The data sample in Problem 5 9.85 9.93| 9.75 | 9.77 | 9.67 | 9.87 || 9.94 | 9.85 | 9.75 9.83 9.92 | 9.74 | 9.88 | 9.95 | 9.95 | 9.93 | 9.92 | 9.89
