An experiment was performed to determine whether the annealing temperature of ductileiron affects its tensile strength. Five specimens were annealed at each of four temperatures.The tensile strength (in ksi) was measured for each. The results are presented in thefollowing table.Temperature (*C)Sample Values75019.72 20.88 19.63 18.68 17.8980016.01 20.04 18.10 20.28 20.5385016.66 17.38 14.49 18.21 15.5890016.93 14.49 16.15 15.53 13.25a Construct an ANOVA table. You may give a range for the P-value.b. Can you conclude that there are differences among the mean strengths?

Each observation in a random sample of 98 bicycle accidents resulting in death was classified according to the day of the week on which the accident occurred. Data consistent with information are given in the following table. x² Day of Week Frequency = Sunday Monday Tuesday Wednesday Thursday Friday Saturday 13 12 12 14 13 18 Based on these data, is it reasonable to conclude that the proportion of accidents is not the same for all days of the week? Use a = 0.05. Calculate the test statistic. (Round your answer to two decimal places.) 16 Use technology to calculate the P-value. (Round your answer to four decimal places.)
