ANOVA Single Factor in Excel does not seem to produce the correct answers, is this a two-factor test? Thanks in advance

A rope manufacturer tested the breaking strength of several types of ropes over a 10-day period. The results of the study are shown in the accompanying table. Complete parts a through c. Click the icon to view the data. a. Test to determine if inserting the day on which the testing was done was necessary. Use an α = 0.10 level of significance. Determine the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: Not all means are equal HA Hd1Hd2 Hd3 = ... = μ10 OC. Ho Hd1 = Hd2d3d10 HA: All means are unequal E. Ho: Hd1 Hd2 = Hd3=d10 HA: Not all means are equal What is the F-test statistic for this test? F = 0.79 (Round to two decimal places as needed.) What is the p-value value for this test? p-value = (Round to three decimal places as needed.) O B. Ho: At least two populations have different means HA: HN =HPE = Hpp O D. Ho: HN =HPE = μPP HA: At least two populations have different means OF. Ho: At least two means are equal HA: All means are unequal
