The 2022 MotoGP race will take place in Indonesia on March 18-20. The racers will compete at theMandalika Circuit, Central Lombok, West Nusa Tenggara (NTB). The Mandalika Grand Prix Association(MGPA) is the organization in charge of this event. Regarding the safety issues, two different medicalevacuation procedures have been proposed to evacuate riders to the hospital if they get into anaccident. To evaluate the two emergency procedures, a study was conducted. A random sample of tenProcedure A revealed a mean of 26 minutes with a standard deviation of 0.2 to get the rider to thehospital. While a random sample of 12 observations from Procedure B revealed a sample mean of 23minutes and a sample standard deviation is 0.31. At the 0.05 significance level, is there a difference inthe mean time of the two medical evacuation procedures?a. State the null hypothesis and the alternate hypothesis.b. Calculate the degree of freedom.c. Develop the interval estimation.d. Based on the interval estimation, can we reject Ho? Explain.e. What is your conclusion?

A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12
The article "A Debate in the Dentist's Chair"+ described an ongoing debate over whether newer resin fillings are a better alternative to the more traditional silver amalgam fillings. Because amalgam fillings contain mercury, there is concern that they could be mildly toxic and prove to be a health risk to those with some types of immune and kidney disorders. One experiment described in the article used sheep as subjects and reported that sheep treated with amalgam fillings had impaired kidney function. (a) In the experiment, a control group of sheep that received no fillings was used but there was no placebo group. Explain why it is not necessary to have a placebo group in this experiment. O Sheep develop kidney diseases from other causes. O People develop impaired kidney functions from other causes. O The experimental subjects were sheep, who would not be aware whether or not they had fillings. O It is hard to get people to sign up for a study involving not filling a hole in their…
The traffic pattern is being analyzed for traffic going into Myrtle Beach on 501. The intersection of US-501 and US-17 Bypass was designed such that 50% of the traffic would continue straight on 501, 30% would go north on 17 Bypass, and 20% would go south on 17 Bypass. Since then, there has been a significant amount of commercial growth around the intersection that may have impacted the traffic flow. A sample of 600 cars is to be reviewed to see if the traffic has significantly changed using the chi-square test. How many cars do you expect to go straight on US-501?
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.
2) 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 is the P^? (round to nearest thousandth)
