1. An experiment using 0.5 grams of fresh garlic and crushed garlic root, leaf and bulb from garlic cloves sprouted for 2 days was performed. The garlic was used in a bioassay on lettuce seedlings to see if growth of the lettuce seedlings was inhibited compared to a control. Data recorded was seedling length in millimeters.

(ii) What is the probability that the difference between the groups is due to chance? e) (i) If the calculated / for the sprouted bulb compared to the fresh garlic is / = 0.33, is the difference significant? (ii) What is the probability that the difference between the two groups is due to chance? 2. An experiment using fertilizer on bean plants was performed. Germinated seeds were planted in sterile soil to which different amounts of a commercial fertilizer was added. Height of the plants was measured in centimeters 25 days after planting. Data recorded was bean plant heights in centimeters (+ 0.5 cm).Group No fertilizer Group By 0:001% fertilizer Group Group D 8 001%% fertilizer 10 offertilizer 10 7 12 8 7 10 13 7 8 15 10 7 10 10 10 8 8 10 7 9 10 15 8 9 10 9 8 8 10 9 6 14 7 9 7 10 a) Find the mean and standard deviation of each set of data. b) Discuss the variability of the bean plant data. c) Compare the means of each group of data. d) (i) If the calculated / for group B compared to the control is / = 0.60, it the difference between the two groups a significant difference? (ii) What is the probability that the difference between the two groups is due to chance? e) (i) If the calculated / for Group D compared to the control is fm = 2.90, is the difference between the two groups significant? (ii) What is the probability that the difference is due to chance
