In a χ2 goodness-of-fit test, the expected value for the ith cell assuming H₀ is true is calculated using the formula (n x p), where n is the total sample size and p is the hypothesized proportion for that cell. Therefore, 11eb86f3_5f7c_2b1a_883a_e55990e57475_TB8195_11 is the expected value for the ith cell assuming H₀ is true.
