A screening test for high intracranial pressure was proposed many years ago, based on the data in the following observations. This simple and non-invasive test involves observing the retinal vein to see if it is pulsating. Pulsation is normal and so would be considered a negative test result.

- What does multivariant normality mean in MANOVA? How is it tested and what do I do if the assumption is not met.proposed research question: Does implementing trauma-informed education in elementary schools affect the rate of student behavior referrals? Based on the proposed research question, state a two-tailed hypothesis.review(8a): Identify the test statistic used for the ANOVA prodcedure and how it is calculated (a) the test statistic is F and is calculated by finding the difference between group means (b)the test staitistic is z and is calculated by finding the mean z score between groups. (c) the test statistic is F and is the ratio of the variation getween groups to the variation within groups. (d) the test statistic is z and is the ratio of the mean within a group to the variation between groups
- The best depiction of a population characteristic is a(an): Dependent variable Statistic Independent variable ParameterTrue or False? A randomized controlled trial evaluates the efficacy of hydroxychloroquine, as compared to placebo, as a prophylactic treatment to prevent COVID-19 infection in high-risk healthcare workers. The study provides data on a number of demographic characteristics and medical conditions at baseline. The mean age of participants randomized to receive hydroxychloroquine was 31 years and the mean age of participants randomized to receive placebo was 34 years, with p = 0.13. We can conclude that there is no statistically significant difference in mean ages of participants randomized to receive hydroxychloroquine as compared to placebo.(only if possible, preferably in minitab, but you can do it manually)
- Diabetes Physicians recommend that children with type-I (insulin dependent) diabetes keep up with their insulin shots to minimize the chance of long-term complications. In addition, some diabetes researchers have observed that growth rate of weight during adolescence among diabetic patients is affected by level of compliance with insulin therapy. Suppose 12-year-old type-I diabetic boys who comply with their insulin shots have a weight gain over 1 year that is normally distributed, with mean = 13 lbs and variance = 13 lbs. (Assume for parts (a) and (b) that weight can be measured exactly and no continuity correction is necessary. Round your answers to four decimal places.) USE SALT (a) What is the probability that compliant type-I diabetic 12 year-old boys will gain at least 17 lbs over 1 year? X (b) Conversely, 12-year-old type-I diabetic boys who do not take their insulin shots have a weight gain over 1 year that normally distributed with mean = 7 lbs and variance = 13 lbs.
