Type I and type II errors

probability of a statistical study depends on the prior probability, statistical power, and the level of the observed P value, it means that the probability of a study finding a true relationship is the power of 1-β (one – type two error (Ioannidis, 2005 page 0696). Also, “type 1 error is the probability of incorrectly rejecting a null hypothesis that should not be rejected” (Wirtz, 2013). Factors that negatively affect the probability of true relationships are small studies, smaller effect sizes, in

post MI? If this result was consistent with previous research, how might you use this knowledge in your practice? The t value tells us about the differences between men and women post MI physical component score. In my practice using this t value, I would be able to work differently between men and women after post MI. Teaching might provide to women more about physical functioning, role physical, bodily pain and general health since these are all included in physical component score. The physical

Explain your rationale. a) Portable home oxygen unit-GY – identifies rental or purchase of durable medical equipment for use in the patient’s home; is statutorily excluded, does not meet the definition of any Medicare benefit or for non-Medicare insurers, is not a contract benefit, is appended to procedures that are excluded from the Medicare

the cancer from spreading to other parts of the body and also reduce breast cancer deaths. Breast tumors can be either “benign” (non-cancerous) or “malignant” (cancerous) and the type of the tumor can be identified by using the Tumor, Nodes and Metastasis (TNM) staging system and the disease stage can range from stage I to stage IV. In the stage 0 (carcinoma in situ), there is a high probability of developing invasive form of cancer in a short period of time. This staging system of breast cancer

Introduction Currently, in the United Kingdom breast cancer is the most common type of cancer in women and early diagnosis is the key to reducing mortality rates (Skaane et al, 2007). The National Health Service breast screening programme introduced digital mammography as the preferred option due to its increased sensitivity and specificity for denser breasts. Additionally, it has the ability to manipulate the images produced (NHSBSP, 2012). The aim of this study is to investigate the relationship

Private employers are not required to follow the SAMHSA guidelines but by doing so they can have better leg to stand on when it comes to the legal field. Many court decisions have been ruled in favor of these guidelines. These guidelines include having a Medical Review Officer (MRO) evaluate all tests. The guidelines also identify the five specific substances for use in the Federal drug testing programs and require a drug lab certified by SAMHSA to perform the analytical test. The five substances

Introduction This study investigated the positive correlation between obstructive sleep apnea (OSA) with an increased rate of postoperative complications including (1) postoperative hypoxemia, (2) intensive care unit (ICU) transfers, and (3) prolonged length of hospital stay in noncardiac surgical patients. OSA patients commonly express cardiac disease, have an increased risk for postoperative morbidity, and OSA is considered an independent risk factor for patient mortality. This study is significant

Keywords:-Spectrum Sensing, Cognitive Radio, Wireless Communication, Energy Detection, Matched Filter, Probability Detection and Threshold. I. Introduction:-The recent trend in cognitive radio-related research has altered s great of deal of interest in spectrum sensing and detection of radio users in the environment [5]. In general, the spectrum user signals are categorized into primary

Out of 100 patients studied in this research, the age incidence varies between 12 to 47 years, the maximum incidence of acute appendicitis was found in age group of 21- 40 years [56 patients (56%)], followed by age group of ≤20 years [28 patients (28%)] and lastly the age group of 41-60 years [16 patients (16%)]. Regarding to sex, males were more than females [68 males (68%) vs 32 females (32%) with a ratio of 2.13:1 respectively]. Married patients were suffering from acute appendicitis more than

3- PET scan findings All of our patients had a mediastinal lymph nodal SUV ≥ 2.5 as per our inclusion criteria. Most of our patients had fallen in the N2 category, representing 73.5% of our patients while N3 represents 26.5%. When we compare this to the post mediastinoscopy nodal state , we found that N3 state had gone up by 5.5% representing 32% of the sample. It was hoped that a PET will provide better results than CT scan. Studies on PET reported a high sensitivity
