Question
- A highway patrol officer believes that the average speed of cars traveling over a certain stretch of highway exceeds the posted limit of 55 km/ hr. A random sample of 10 cars had their speeds measured by radar. The results in Km / hr are as follows:
71, 53, 62, 49, 59, 52, 58, 61, 85, 55
Do these data provide sufficient evidence to support the highway patrol belief, at the 10% level of significance?

- In the Star and Tribune newspaper, there is an article entitled "1 in 8 school buses fail tests." The article says that the overall statewide proportion of school buses that fail safety tests is 9%. However, one bus company has a higher rate of over 12%. Assume that we want a new estimate for the statewide proportion of school buses that fail the safety inspection. We take a sample of 500 buses and find that 90 buses fail the safety inspection. Based on the new sample data, I construct this 90% confidence interval estimate for p: 152 < p < .208. Explain what this confidence interval means. O I am 90% sure that the number of buses that fail the inspection is between.152 and .208. O I am 95% sure that the true proportion of buses that fail the inspection is between .152 and .208. O I am 90% sure that the proportion of buses in this sample that fail the inspection is between .152 and .208. O I am 90% sure that the true proportion of buses that fail the inspection is between .152 and .208.arrow_forwardHi, Can you please answer E) to this question?

- A survey was conducted among the engineering students in a university. The survey is conducted to find the relationship between the test preparation time and their test achievement. The 50 respondents were asked 2 questions: a) How much time did you spend to prepare for the exam? and b) What is your test achievement? Based on the above statement, determine the type of statistics that is suitable for the study and briefly explain your answer.arrow_forwardTwelve inmates in a particular prison took part in an anger management class.
