A doctor wants to estimate the mean hdl cholesterol of all​ 20- to​ 29-year-old females. How many subjects are needed to estimate the mean hdl cholesterol within points with confidence assuming based on earlier​ studies? suppose the doctor would be content with confidence. How does the decrease in confidence affect the sample size​ required?.

Answers

Answer 1

The sample size required is a minimum of 30 participants.

What is the ideal number of participants?

Whenever the study sample size is very restricted (<30 measurements), the analysis of subgroups is difficult and the performance of statistical tests is compromised. However, additional care must be taken with sample oversizing, which commonly occurs when accessing large computerized databases. The increase in the sample reduces the confidence intervals of the estimates and allows the detection of differences between subgroups that, despite being statistically significant, are not clinically relevant.

With this information, we can conclude that The sample size required is a minimum of 30 participants.

Which feature of influenza viruses is the reason why vaccines against them have to be produced each year

Answers

The feature of the influenza virus which is the reason behind synthesis of new vaccines for influenza every year is antigenic drift.

Antigenic drift is a phenomenon by which mutations give rise to genetic variations in pathogenic agents like viruses, which changes the viral surface proteins of the virus. These changes in the viral surface proteins in the antigen leads to the generation of new variations. These variations are new to the immune cells in the body and trigger them with different signals every time they infect a host.  The best example to study this effect is the influenza virus which has numerous variations like influenza A, B, C and D. Thus, the influenza virus has to be produced or updated every year.

During properly performed external chest compression on children under 8 years old or on large toddlers, how much should the sternum be compressed

Answers

During external chest compression on children under 8 years old the sternum should be compressed about 1/3 to 1/2 the depth of the chest.

Cardiopulmonary resuscitation is known as CPR. When a child's respiration or heartbeat stops, it is a life-saving surgery.  

Compress the breastbone. For a baby or infant, press down 4 or 5 cm, or around one-third of the chest's diameter. At a rate of around 100–120 compressions per minute, quickly release the pressure before repeating. When we've completed 30 compressions, tilt the head, elevate the chin, and take two deep breaths. For adults, compress the chest to a depth of at least 2 inches. Allow the chest to fully rise each time. These compressions must be swift, forceful, and uninterrupted.
