A horticulturist working for a large plant nursery is conducting experiments on the growth rate of a new shrub. Based on previous research, the horticulturist feels the average weekly growth rate of the new shrub is 3 cm per week. A random sample of 48 shrubs has an average growth of 2.70 cm per week with a standard deviation of 0.60 cm. Is there overwhelming evidence to support the claim that the growth rate of the new shrub is less than 3 cm per week at a 0.025 significance level? Step 3 of 3: Choose the best option below that describes the statistical and practical significance of this test. Answer ○ The test was both statistically and practically significant. Tables Keypad Keyboard Shortcuts O Although the test was not statistically significant, there is a practical difference between a growth rate of 3 cm and 2.70 cm. ○ Although the test was statistically significant, there is no practical difference between a growth rate of 3 cm and 2.70 cm. ○ The test was neither statistically nor practically significant.
