Steve, age 79, has GERD. When teaching him how to reduce his lower esophageal sphincter pressure, which substances do you recommend that he avoid?A. applesB. peppermintC. cucumbersD. popsicles

Answers

Steve, age 79, has GERD. When teaching him how to reduce his lower esophageal sphincter pressure, substances that he should avoid is peppermint. The correct answer is B.

Steve, who has GERD (gastroesophageal reflux disease), should avoid substances that can reduce his lower esophageal sphincter pressure and worsen his symptoms. One such substance is peppermint, which is known to relax the lower esophageal sphincter and can contribute to acid reflux.

Therefore, it is recommended that Steve avoid peppermint in order to reduce his lower esophageal sphincter pressure and alleviate his GERD symptoms. Apples, cucumbers, and popsicles are not known to have the same effect on the lower esophageal sphincter and are therefore not recommended for Steve to avoid.

What is the branch of psychology that emphasizes human strengths?

Answers

The branch of psychology that emphasizes human strengths is called positive psychology. Positive psychology focuses on studying positive emotions, and seeks to understand how individuals and communities can thrive and flourish.

Instead of focusing on the negative aspects of human experiences, such as mental illness or dysfunction, positive psychology examines the factors contributing to well-being, happiness, and optimal functioning.

Positive psychology has roots in the humanistic psychology movement of the 1950s and 60s, which emphasized the importance of personal growth and self-actualization. However, positive psychology is distinct from humanistic psychology in that it is a scientific approach to studying human strengths, employing rigorous research methods to explore topics such as resilience, creativity, gratitude, and meaning in life.

according to social scientists, social and economic inequality can affect the spread of an epidemic such as covid-19.?

Answers

The remark of social scientists on spread of Covid 19 epidemic due to social and economic inequality is true because economic gap was one of the main reason for many not being able to procure treatment, beds in hospital and food for themselves (as they lost jobs).

The Covid 19 epidemic has risked and costed the lives of many people all over the families. Most of the families lost one or the other member due to Covid 19. It was mainly due to lack of information to prevent oneself from it, lack/ shortage of medicines and vaccines and even the low awareness among the people.

While rich people were able to afford expensive treatment, home isolation and collection of basic living needs to sustain their lives, the poor were roaming on the roads begging for help, or along the dead bodies of their relatives because there was no space left for burning or cremating them.

The society prohibited from contacting one another due to the fear of diseases, and those who could extend some help stayed away from people who were poor and could not even afford some basic precaution kit such as high quality masks, sanitizers, face shields etc. It was this disparity which highlighted that though many died of the disease, there were many others who died due to shortage of food to feed their family in the lockdown.

It is one of the most inhumane situation that everyone in the world witnessed and despite the support they could give, they tried to stay disconnected from one another to help prevent spread of diseases.

Answers

Best defines the notion of the significance level of a hypothesis test is the probability of the type I error.

The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true.

Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data. The test provides evidence concerning the plausibility of the hypothesis, given the data. Statistical analysts test a hypothesis by measuring and examining.

The most common null hypothesis test for this type of statistical relationship is the t test . In this section, we look at three types of t tests that are used for slightly different research designs: the one-sample t test, the dependent-samples t test, and the independent-samples t test.

To conduct the hypothesis test for the population mean μ, we use the t-statistic t ∗ = x ¯ − μ s / n which follows a t-distribution with n - 1 degrees of freedom.
