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 5 26 32 18 38
data are given below. At the 10% significance level, do the data provide sufficient evidence to
conclude that a difference exists in mean bacteria counts among the five strains?
T, = 102, T2 = 130, T3 = 188, T4 = 96, T5 = 190, and Ex = 25,824

Let u1. H2. H3, H4, and g 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: H1 # H2 # H3 # H4 # Hs

Hạ: Not all the means are equal.
O D. Ho: H1 = H2 = H3 = H4 = H5
Ha: H1 # H2 # H3 # H4 # Hs
