*24. One facet of a company's expertise is the development of dielectric fluids in electrical equipment. Mineral oil-based dielectric fluids have been used more extensively than other dielectric fluids. Their only shortcomings are their relatively low flash and fire point. One study examined the fire point of mineral oil, high-molecular-weight hydrocarbon (HMWH), and silicone. The fire points for each of these fluids are recorded in the following table. Assume that the data are approximately normal. Complete parts a and b. Click the icon to view the sample data. a. Develop the appropriate ANOVA table to determine if there is a difference in the average fire points among the types of dielectric fluids. Use a significance level of 0.01. Identify the hypotheses for the test. Choose the correct answer below. OA. Ho: H1 H2 H3 HA: All of the population means are equal OB. Ho: H1 H2 H3 HA: At least two of the population means are equal OC. Ho H H =3 HA: All of the population means are different OD. Ho H = H3 HA: At least two of the population means are different State the decision rule at the = 0.01 level of significance. Select the correct choice below and fill in any answer boxes in your choice. (Round to three decimal places as needed.) A. If F> OB. If F < C.
