Do certain car colors attract the attention of the police more than others, so that they are more likely to get speeding tickets? A few years ago a curious newspaper columnist tabulated the car color on a random sample of 120 speeding citations at the local courthouse. Here are his results: Color Red White/Silver Gray/Black Other Number of Speeding Tickets 16 33 39 32 He then went to the state motor vehicle registry and obtained data on the distribution of car colors for all cars registered in his state: Red 14%, White/Silver 35%, Gray/Black 23%, Other 28%. To answer the question poised above about car color and speeding tickets, the appropriate null hypothesis is: Group of answer choices: -The observed counts are equal to the expected counts. -At least one of the four car color percentages is different from the other three. -The observed counts are all equal to 30 -The distribution of car colors for the speeding citations is the same as the distribution of colors for cars on the highway. -The observed number of speeding tickets is the same for all four color groups
