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-like protein in the soil surrounding the onions' roots. Lectins often accelerate mitosis in root systems, but this abnormal growth creates weaker plant tissues. Three samples of 25 cells each were observed from the struggling onion crop. The observed number of cells in each part of the cell cycle are shown below: a) State the null and alternative hypothesis related to the data. b) Calculate the chi-square values for interphase and mitosis using your trial one data in table 3 as the expected data (e). These cells are normal, onion root tip cells. Use the sample data above as the observed values \( (\mathrm{o}) \). These samples were exposed to lectin. 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). d) Based on the chi-square and critical value, draw a conclusion about the null hypothesis.

Given that, (a) The null and alternative hypothesis are Null Hypothesis H0:All values are in
