An advertising company conducted research to see the number of people speeding through a particular stretch of road. They found that of the 2500 cars that went through that section that day that 529% of them were speeding by at least 5 km/h. The distribution of speeds going through this stretch was normally distributed. To see if the effect of having a sign showing your speed was helping the problem, they conducted a survey of 200 cars one day and found that 45% were speeding through that section by at least 5 km/h. With a level of significance of 0.05, can we conclude that this sign is helping to reduce the number of people speeding through this section of road? Conduct a 5 step hypothesis test (step 6 is not needed)
