Transportation engineers determined that to help ease traffic, they would set up tolls for solo drivers during rush hour times on Route I-66 inside the Capital Beltway (I-495). Carpooling drivers with the proper Ezpass would drive free. The toll program began in December 4, 2017. To test the claim that fewer vehicles would use Route I-66 after the program began, a count of the number of vehicles were collected from two random samples. Both samples were taken on the first Monday of each month for an entire year before and after the toll program was implemented. The data set is called "Number of Vehicles 2" and we will use a = investigation. 0.05 in this

1.) Create a set of hypotheses for a test.
A researcher selects a sample of international students and provides them with extra support to pursue their educational goals. The graduation rates for the sample is compared to the graduation rates for international students overall. In this study design, what are the null and alternative hypotheses? answer should be in the form of 2 complete sentences.
Express the null hypothesis and the alternative hypothesis in symbolic form. An entomologist writes an article in a scientific journal which claims that fewer than 12 in ten thousand male fireflies are unable to produce light due to a genetic mutation.
A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness. Identify the null and alternative hypotheses. A) Ho: p 2 5.8% B) Họ: p > 5.8% C) Họ: p 5.8% H1: p2 5.8%
16% of workers got their job through internet resume sites. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage).
If a hypothesis is not rejected at the 5% level of significance, it a) will always be rejected at the 1% level O b) will also not be rejected at the 1% level O c) will sometimes be rejected at the 1% level d) None of these alternatives is correct.
5) Rafting down two different rivers took place, 324 boats rafted down the first river, and accidents (capsizing, boat damage, etc.) happened to 35 of them. 92 boats rafted down the second river, and accidents happened to 18 of them. (i) The second river is considered to be more complicated route to raft. Is there evidence for this assumption? Write the null and alternative hypotheses? (Hint: Compare two population proportions) (ii) Use appropriate test statistic to test the hypothesis. Use a = 0.10. ( test statistic in 4 decimal place, critical region for the test statistic) (ili) Construct a 90% one-sided confidence limit for the difference in proportions that can be used to answer the question in part (ii) of 5b) question. ( the bound obtained on the difference in proportions in two decimal place)
The mean weight of male aerobics instructors in a certain city is less than 185 lbs. Express the null and alternative hypotheses in symbolic form for this claim.
Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.
Historically, about 70% of all U.S. adults were married. A sociologist who believes that marriage rates in the United States have declined will take a random sample of U.S. adults and record whether or not they are married. a) State the null and alternative hypotheses in words. b) Let p represent the proportion of all adults in the United States who are married. State the null and alternative hypotheses in terms of this population parameter.
