- Use the average method to forecast enrollment in Spring 2022What is Scatterplot?A university is trying to determine how many of their students have watched a bystander intervention video aimed at reducing assault on campus. After posting the video to their social media, some school officials mention in passing that if it is not widely viewed, it may become a requirement to attend in-person trainings. In an effort to gauge how many students have viewed the video, the administration sends a survey to all students on campus (about 3500 students). About 30% of students choose to respond to the survey, producing a sample size of N = 1050. About 70% of the student respondents stated that they had watched the video. From this data, the administration concludes that their sample is large, it represents the whole student population, and therefore 70% of all students had watched the video. As a result, the in-person training is not warranted. Why is this a problematic conclusion to draw? In your answer, be sure to address the type of sample that was obtained, why it may be…
- construct anova and show all calculation manually, thanksA national survey of 1,000 adults conducted on August 2-10, 2017 from CompareCards, conducted by Google Surveys, found that Americans trust cash the most (36 percent) for everyday purchases outside the house. When separated by age, it turns out that millennials trust cash the most, whereas baby boomers and older generations trust their credit card the most for everyday purchases. What is most likely the population?What is formula for degree of freedom?
- It is the collection of all outcomes,responses,measurement or counts that are of interestHurricane Andrew swept through southern Florida causing billions of dollars of damage. Because of the severity of the storm and the type of residential construction used in this semitropical area, there was some concern that the average claim size would be greater than the historical average hurricane claim of $23,000$23,000. Several insurance companies collaborated in a data gathering experiment. They randomly selected 2222 homes and sent adjusters to settle the claims. In the sample of 2222 homes, the average claim was $24,500$24,500 with a population standard deviation of $4100$4100. Is there sufficient evidence at a 0.010.01 significance level to support the claim that the home damage is greater than the historical average? Assume the population of insurance claims is approximately normally distributed. Compute the value of the test statistic. Round your answer to two decimal places.Several years ago, the Arcadia school system was criticized because the average Arcadia High School graduate could read at only the ninth-grade level. After this report was made, a special reading program was established to upgrade skills. The AHS principal wants to know if the reading program worked. If it has, he will request that an accreditation team visit the school. If the program has not improved the reading level to at least 10.0 (sophomore level), the administrator would like to avoid the embarrassment of a poor review. To determine the average reading level of the senior class, we select ten seniors at random. We assume that reading scores are normally distributed. The reading scores for the ten seniors are shown in Table 1.
