In a large city, 130 randomly selected adults with children and 170 randomly selected adults without children were asked which type of car best describes the vehicle they primarily drive: car, truck, van, or SUV. The observed and expected counts are in these tables. The value of the chi-square test statistic is 5.47. Here is a chi-square distribution table. Select all statements that are true. df = 3 df = 7 The P-value of this test is less than 0.05. The P-value of this test is greater than 0.05. We should reject H0. We fail to reject H0. There is convincing evidence at α = 0.05 that the distribution of type of vehicle driven differs between adults with children and adults without children.
