3. If you need assistance on chi-square hypothesis testing for the question below, refer to the pre-lab activity of your lesson. Agriculturalists investigating a poorly growing onion crop discovered it was infected with a fungal pathogen. The fungus secreted a lectin-lilce protein in the soil surrounding the onions' roots. Lectins often accelerate mitosis in root systems, but this abnormal growth creates weaker plant tissues. Fifty cell samples were observed for the struggling onion crop. The observed number of cells in each part of the cell cycle are shown below: Sample One l Sample Two l Sam le Three I Interphase 21 18 I25 Mitosis 29 32 25 a) State the null and alternative hypothesis related to the data. b) Calculate the chi-square values for interphase and mitosis using the samples as the observed values (0) and trial I in table 3 as your expected data (e). c) Using the chi-square table, determine the critical value for interphase and mitosis of the struggling onion crop using the chi-square values in (b).
