In April of 2019, HB 437 was approved in the state house of representatives which would require middle school-and high school-students to learn about the Holocaust and other genocides.  Some believe that students are not aware of the Holocaust, then the curriculum should be revised to correct that deficiency.  A recent survey of 506 high school students showed that 268 of them did not know that the term “Holocaust” refers to the Nazi killing of about 6 million Jews during World War II.   Using the sample data and a 0.05 significance level, test the claim that more than 50% of high school students are unaware of the Holocaust.  (Be sure to write all steps with conclusions in full sentences.)

A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 19 offspring birthed.They then observe that 13 are female.Use a sign test to test the indicated hypothesis.What is the obtained value?

There are 9 million enrollees in the Department of Veterans Affairs health care system. It wants doctors and nurses to treat pain as a “fifth vital sign” to be recorded along with blood pressure, pulse, temperature, and breathing rate. If you were to aid the VA in this situation, how would you measure a patient’s pain? How could this “fifth vital sign” be a potentially invalid measure? Answer each question with at least one paragraph of three complete sentences.

In recent years, many states have enacted tougher voter identification laws requiring a government issued photo ID. Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws. Document your work in the space provided below. Document how you computed the margin of error and the confidence interval in the space provided below. Round all numbers to 4 decimal places. 2)Is it likely that three-fourths of adults approve of these new laws?

Throughout the world, women are targets of harassment, discrimination, violence, and evenmurder due to perceptions of their clothing choices. Some women are targeted because theydress to religious and some women are targeted because they do not dress religious enough. Aresearcher was interested in determining if countries that had more restrictions on how womendress (i.e., how many laws regulate women’s clothing choices?) also had more women reportingsocial hostility from others (e.g., discrimination, abuse, violence). What statistical test should beused to determine if there is a relationship between number of women’s clothing regulations andthe number of reports of social hostility? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B. What would be the appropriate statistical test? Explain your rationale.

1) The rabies vaccine for dogs can save your dog's life. If your dog bites another animal or is on the receiving end of a bite, the vaccine can protect them from a dangerous and potentially fatal illness. Furthermore, in most places, the rabies vaccine for dogs is legally required. The NYC Department of Health wants to know if LESS than 95% of the dogs in the city have been vaccinated with their rabies vaccine.  158,045 of the 165,000 dogs examined had their rabies shots.  Risk no more than 5% Type I error.  What are the hypotheses? Null and Alternate

For the time being, the air traffic control system in the United States is run by the federal government. Several groups disagree with this and would like to privatize the air traffic control system. Among the arguments given for privatization is that flight delays are much too common in the United States. A first step in deciding if, indeed, delays in the U.S. are "too common" might be to compare the flight delay information from the U.S. and other nations. You have in front of you the following chart, which summarizes the information from three samples of flights from the past six weeks. One of the samples is composed of domestic U.S. flights, one is composed of domestic Canadian flights, and one is composed of domestic British flights. The information recorded for each flight is the time (in minutes) that the plane was late to the arrival gate. (If the plane was early, the time recorded was negative.)
