Can someone help me with Probability and Confidence Intervals?

Question 4 Use the following probability model to answer the question. Event: For each adult resident in a city we ask how many vehicles they own. Probability Find the probability that an adult resident has 3 or more 1vehicles. Give your answer as a number between D and 1. Question 5 1.5 pts Use the following probability model to answer the question. Event: For each adult resident in a city we ask how many vehicles they own. Number of Vehicles Probability 0 0.04 0.41 2 0.38 3 0.13 4 0.03 5 0.01 Find the probability that an adult resident does not own a vehicle. Give your answer as a number between 0 and 1.Question 6 1.5 pts You asked a sample of individuals what kind of animal is their favorite. Of the 167 individuals in your sample, 52 of them answered "dog". Which of the following gives a 95% confidence interval for the true percentage of individuals whose favorite animal is a dog. O (23.4%, 38.9%) O (16.8%, 32.36) O (3.16%, 3.26%) O (2.21%, 4.216) Question 7 1.5 pts A news article reports that 52% of voters plan to vote for Vicente and 48% of voters plan to vote for Raul. The margin of error is 3%. Is there enough statistical evidence to say that Vicente is in the lead? O Yes. Because the confidence intervals don't overlap we have enough evidence to say the parameters are different. O Yes. Because the confidence intervals do overlap we have enough evidence to say the parameters are different. O No. Because the confidence intervals don't overlap we do not have enough evidence to say the parameters are different. O No. Because the confidence intervals overlap we do not have enough evidence to say the parameters are different.Question 2 1.5 pts Last year, 631 of the 1,822 residents in a small town owned more than one vehicle.
