Five strains of bacteria were observed for 24 hours. The table given to the right reports bacteria counts, in millions, for different cases from each of the five strains. Some summary statistics for these data are given below. At A B C D E the 10% significance level, do the data provide sufficient evidence to conclude that a difference exists in mean bacteria counts among the five strains? 3 35 36 20 36 talGeys T1 = 103, T2 = 127, T3 = 189, T4 = 95, T5 = 190, and Ex, = 24,500 30 32 45 16 47 10 19 44 22 31 GEYSER S WATER 4 22 22 18 48 led at urce. 56 19 42 19 28 wformation contact mail at om sure ken Let H1, H2, H3, H4, and us be the population means for strains A, B, C, D, and E, respectively. What are the correct hypotheses for a one-way ANOVA test? O A. HO: My # H2 # H3 # H4 # 15 O B. HO: H1 = H2 = H3 = H4= H5 Ha: H1 = H2 = H3 = H4 = H5 Ha: H1 # H2 # H3 # H4 # H5 O C. Ho: H1 = H2 = H3= H4 = H5 OD. HO: H1 # H2 # H3 # H4 # H5 Ha: Not all the means are equal. Ha: All the means are equal. Determine the F-statistic. F = (Round to two decimal places as needed.) Determine the P-value. P-value = (Round to three decimal places as needed.) Since the P-value is the significance level, Ho. The data sufficient evidence to conclude that the population means are not all the same
