Researchers studied the effect of a houseplant fertilizer on carrot sprout growth. They randomly selected some carrot seeds to serve as controls, while others were planted in aluminum planters to which fertilizer sticks were added. Other conditions were held constant between the two groups. The following table shows data on the heights of plants (in cm) 2 weeks after germination. Use attest to investigate whether the fertilizer has an effect on average carrot sprout growth. Use a = 0.05.
