- It is known through Operation Laban Altapresyon that 15% of adults from the Province of Realeza are hypertensive. Princess recently conducted a survey to determine the prevalence of high blood pressure among the towns of the Province of Realeza. Her findings are tabulated below.Twenty samples, each consisting of 100 admission applications at a university, resulted ina total of 80 applications that had some type of error. Compute the control limits for ap-chart. What would be the impact on the final results if each sample contained 200 loanapplications rather than 100 and all other data remained the same? Please show in detail these impacts quantitatively in your answers.Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that more than 60% of those with diabetes who undergo this surgery will recover from diabetes? Use a 5% level significance.
- Evaluate the source for reputability, transparency, andbeing evidential. Scenario: In a study conducted by the Pew Research Center, 681 university students were surveyed. Of those surveyed, 32% reported experiencing food insecurity - and going without food to pay for textbooks and housing instead. Short answer A. The exact question reads "Within the last 30 days, have you gone without food to pay for textbooks or housing instead?": describe the type of data collected by this question as precisely as possible. B.University administrators were expecting a proportion closer to 9%. Without resortingto any analysis methods, does it appear that the result has statistical significance?can someone help me please? Does it surprise you that higher percentages of the participants in the NSSI group engaged in health-risk behavior than participants in the non-NSSI group? Explain.? or For the non-NSSI group, the percentages in Table 1 sum to more than 100%. Explain how this is possible.Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage. What is the explanatory variable? A. Survival without brain damage B.Infants whose brains are temporarily deprived of oxygen C. Usual care or whole-body cooling
- A random sample of 113 felons convicted of nonviolent crimes in a state prison system completed a program designed to improve their employment possibilities before being released on parole.

A new type of screening for lung cancer, computed tomography (CT), has been developed. Medical researchers believe CT scans are scans are more sensitive than regular X-rays in pinpointing small tumors. The Cancer Center at the University of South Florida is currently conducting a clinical trial of 50,000 smokers nationwide to compare the effectiveness of CT scans with X-ray for detecting lung cancer (Today’s Tomorrows, Fall 2002). Each participating smoker is randomly assigned to one of the two screening methods, CT or chest X-ray, and his or her progress is tracked over time. The age at which the scanning method first detects a tumor is the variable of interest. A. Identify the data collection method used by the cancer researchers. B. dentify experimental units of the study. C. Identify the type of the variable measured. D. Identify the population and sample.The definition and composition of families has evolved over the past several decades. The PewResearch Center (2020) published a report of some of the generational differences, including theproportion of men who are not married and living with their own child(ren). A researcher isinterested in determining if there is a significant difference between the number of single fathersin the Baby Boomer generation and the Millennial generation. To do this, they are going tocompare the proportion of fathers who report being unmarried and living with their child(ren) in2019 – for the Millennial generation – and 1987 – for the Baby Boomer generation. Whatstatistical test should be used to determine if there are differences between the two generations?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.
