Rice is one of the most widely consumed grain worldwide As increasing global temperatures hamper rice production scientists are searching for varieties exhibiting some degree of heat resistance The HT54 variety of the indica rice Oryza sativa was found to tolerate several days of high temperatures up to 48 C 118 F during its growth Researchers performed a genetic crossing experiment between the heat resistant HT54 variety and a control variety HT13 without heat resistance All seedlings in the first generation survived a heat challenge of 48 C However only 548 of the 744 plants in the second generation survived the heat challenge This suggests that heat resistance is carried by a single gene with a dominant allele and a recessive allele in which case the rice phenotype marked by heat resistance should theoretically occur in 75 of the seedlings Calculate the chi square statistic for this scenario Enter your answer rounded to three decimal places
