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) z- test B) t - test C) test independent samples D) T - TEST RELATED SAMPLES E) ANOVA F) FACTORIAL ANOVA G) repeated measures ANOVA H) pearson correlation i) chi square
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.

A local bank has two branches in a cty: one in the business center of the city and another-in a residential area. The bank's operations manager wants to Improve front-office employee scheduling during the lunch hour (12:00-13:00) period. The manager starts with studying the customer walting times at the two branches and collects data for two groups of 35 customers at each branch. Customers at the business-center branch walted on average 3.8 minutes, whle those at the residential branch waited 4.4 minutes on average, Assume that the population standard deviations are 1.8 (business-center branch) and 2.5 tresidential branch). a. Considering the real-ife problem, determine the point estimate of the unknown quantity that needs to be estimated. (Round to two decimal places.) b. Determine the critical value needed to compute a Bs confidence interval (Round to two decimal places.) c. Compute the confidence interval the operations manager would be interested in computing using the confidence…
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
