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.

Question

(a) Compute the sample mean and the sample standard deviation of the data set.

(b) Define the parameter of interest and state the relevant hypotheses.
(c) Perform hypothesis testing by calculating the p-value in this case, and what
would you conclude at significance level α= 0.05?

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.
