To compare the effects of four different chemicals in producing water restance in textiles, a strip of material randomply selected from a bolf of chemical was cut ito four pieces were randomply assigned to receive an application of one of the chemicals A, B, C, or D. Low readings indicate low moisture penetration. Refer to the table below. Is there a significant difference among the four chemicals? Write Fobserved in terms of bolt samples. Use 6 decimal places in your final answer. Write zero before the decimal point if the answer is less than one. Bolt Samples 1 2 3 Chemical 10.1 12.2 11.9 A Chemical 11.4 12.9 12.7 В Chemical 9.9 12.3 11.4 Chemical 12.1 13.4 12.9

How could you use a random-digit generator or random-number table to simulate rain if you knew that 30% of the time with conditions as you have today, it will rain? Choose the correct answer below. O A. Let the digit 3 represent "rain," and let any other digit represent "no rain." Generate random digits and record the results. O B. Let the digits 1, 2, and 3 represent "rain," and let the digits 4, 5, 6, 7, 8, 9, and 10 represent "no rain." Generate random digits and record the results. OC. A random-digit generator or random-number table cannot be used to simulate rain. O D. Let the digits 0, 1, and 2 represent "rain," and let the digits 3, 4, 5, 6, 7, 8, and 9 represent "no rain." Generate random digits and record the results.
