6. Some researchers have conjectured that stem-pitting disease in peach tree seedlings might be controlied with weed and soil treatment. An experiment was conducted to compare peach tree seedling growth with soil and weeds treated with one of two herbicides. In a field containing 20 seedlings, 10 were randomly selected from throughout the field and assigned to receive Herbicide A. The remaining 10 seedlings were to receive Herbicide B. Soil and weeds for each seedling were treated with the appropriate herbicide, and at the end of the study period, the height (in centimeters) was recorded for each seedling. A box plot of each data set showed no indication of non-Normality. The following results were obtained: (cm) 94.5 109.1 s. (cm) 10 Herbicide A Herbicide B Suppose we wished to determine if there is a significant difference in mean height for the seedlings treated with the different herbicides. Based on our data, which of the following is the value of test statistic? (A) 14.60 (B) 7.80 (C) 3.43 (D) 2.54 (E) 1.14
