Question

In a study of investigating the effectiveness of a new fertilizer to speed up growth in plants, 32 plants were given the new fertilizer. Their average height was 20.00 inches with a variance of 13.00. In addition, 32 other plants in a control group were given the standard fertilizer. Their average height was 11.75 inches with a variance of 11.00. Evaluate whether or not the fertilizer increased growth at the .05 level of significance.
