In an outpatient clinic, a nurse practitioner observes a high prevalence of obesity in young female patients. The nurse practitioner further observes that there appears to be an association between the economic status of the patient and their obesity. The nurse practitioner reviews the related literature but does not find a study that directly relates obesity and economic status. The nurse practitioner decides to conduct a study to determine if a relationship exists between obesity in younger females, ages 15 to 18 years, and their economic status. The nurse practitioner elicits help from four outpatient clinics and receives data on the Body Mass Index (BMI) for all female patients from age 15 to 18 years. The nurse practitioner also attains information concerning if the patient is above or below the federal poverty line for their respective family. The nurse practitioner uses a bivariate correlation between BMI and the dichotomous variable of economic status. The results did not reflect a statistically significant relationship.

Answer #1

Solution:-

A)

This is a case of observational investigation as it records the data about subjects without applying any treatment to subjects.

B)

Here the invalid hypothesis=Ho=Relationship does not exists among heftiness and their monetary status in more youthful females ,matured 15 to 18 years.

Then again or Research hypothesis=Ha=Relationship exists among heftiness and financial status in more youthful females matured 15 to 18 years.

Factors in the investigation are BMI (nonstop factor) and Economic status (dichotomous variable).

C)

Internal legitimacy this investigation can not deduce the circumstances and logical results relationship,as for that we need an exploratory setting i.e., study won't probably establish that financial status caused high or low BMI.

Outer legitimacy If the expert haphazardly chose the 4 outpatient centers for gathering the BMI and monetary status information, at that point we can say that outcomes can sum up to populace.

In any case, in the inquiry ,the irregular watchword isn't referenced.

D)

The professional utilized bi variate relationship between's the BMI and the dichotomous variable of monetary status.

E)

In the event that I were going to direct the study,i would arbitrarily choose the outpatient centers to gather BMI and financial status data.If number of facilities can be expanded that would be useful for the insights.

The t-test method can be utilized to proportion of the result of the investigation as here we have to decide if the 2 gatherings dependent on dichotomous monetary status are unique.
