INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: BMI) if a researcher would like to determine if there is a significant difference in the "BMI" before ("Pre") and after ("Post") the treatment or therapy? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the "BMI" before ("Pre") and after ("Post") the treatment or therapy? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the "BMI" before ("Pre") and after ("Post") the treatment or therapy? 2. What is the computed Mean of "Pre" on the given data for BMI? Round it off to two decimal places. 3. What is the computed Standard Error of "Post" on the given data for BMI? Round it off to two decimal places.
%3D Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 99.21, y = 101.2, r= 0.698, P-value = 0.000, and y = 21.92 + 0.8x, where x represents the IQ score of the older child. Find the best predicted value of y given that the older child has an IQ of 92? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of y is. (Round to two decimal places as needed.)

Teacher claims that the mean time required to complete a Test is two hours. A sample of 10 students took 1.7, 1.5, 2.6, 2.2, 2.4 2.3, 2.6, 3.0, 1.4 and 2.3 hours to complete the test. Test his claim to see if the mean time to complete the Test is different from two house. Use alpha = 0.05. Find p-value. State your hypothesis and your conclusion.
Instrumentation & Measurements This homework measures your capability to design/analyze various components/variables of ameasurement system based on what you have studied. Question is Attached in image. A control system wasinstalled to regulate the weight of potato chips dumped into bagsin a packagingoperation. Given samples of 15 bags drawn from the operation before and after the control systemwas installed, evaluate the success of the system. Do this by comparing the arithmetic mean andstandard deviations before and after. The bags should be 200 g.Samples before: 201, 205, 197, 185, 202, 207, 215, 220, 179, 201, 197, 221, 202, 200, 195Samples after: 197, 202, 193, 210, 207, 195, 199, 202, 193, 195, 201, 201, 200, 189, 197
Use the confidence interval to find the margin of error and the sample mean. (1.77, 2.01) The margin of error is
☐True ☐False The median is a better measure of central tendency when the data is skewed positively, but not when it’s skewed negatively.

Based on the tables can you write or describe a summary for each? Thank you. Descriptive statistics of Sample Characteristics, Drug Use and Mental Health Bivariable Analyses Multivariable Analyses In this study we assess lifetime and recent drug use patterns among 261 heterosexually identified 18- to 25-year-olds through brief street intercept surveys conducted in New York City. Marijuana, hallucinogens, powder cocaine, and ecstasy were the most frequently reported drugs for both lifetime and recent use. Findings further suggest significant differences in lifetime use along the lines of gender, race=ethnicity, and school enrollment for various drugs. Males reported using significantly greater numbers of different drugs compared to females, as did those not enrolled in school compared to school enrollees. These data suggest that illicit drug use in emergent adulthood does not develop in a monolithic manner and synergies must be considered in relation to gender, school enrollment, and…
