The shrubs were grown from a random sample of seeds, and they were all grown in the same soil mixture and in the same size pot. To ensure that any slight differences in the environmental conditions throughout the greenhouse are not confounded with species, she randomizes the location of the pots throughout the greenhouse. The table contains a summary of Macmillan Learning her data. Population Population Sample Sample Sample description size mean standard deviation Species 1 n1 = 20 X1 = 13.749 cm/year $1 = 2.160 cm/year Species 2 n2 = 20 X2 = 16.619 cm/year $2 = 4.284 cm/year A W N Species 3 n3 = 20 x3 = 13.608 cm/year $3 = 3.396 cm/year Species 4 n4 = 20 X4 = 12.769 cm/year $4 = 2.683 cm/year The growth rate distributions of each sample are approximately normal, and the data do not contain outliers. The horticulturist uses a one-way analysis of variance (ANOVA) at a significance level of a = 0.01 to test if the mean growth rates of all four species are equal. Her results are shown in the table.
