Answer:
Dementia develops over time, with a slow progression of cognitive decline. Delirium occurs abruptly, and symptoms can fluctuate during the day. The hallmark separating delirium from underlying dementia is inattention. The individual simply cannot focus on one idea or task.
Paresis is a condition in which muscle movement is weakened. Unlike paralysis, individuals with paresis still have some control over the affected muscles.
Paresis occurs due to nerve damage, which can be caused by a variety of factors or conditions.
Since sample a has data more tightly clustered about the mean compared to sample b, we can say that the variance for sample a is lower than that for sample b.
What is variance:
Variability gets used to measure the central tendency's closeness to the values. A measure of central tendency that can get used is mean. Mean refers to the average for some given values and gets determined by dividing the sum of those values by the number of values. The variance refers to the average squared difference of each value from the mean.
When the variance is lower, the data is less spread out. Thus, data being more tightly clustered about the mean reflects lower variance. Since sample a has data more tightly clustered about the mean compared to sample b, it can be concluded that the variance for sample a is lower than that for sample b.

<h3>Healthcare </h3>
Healthcare can simply be defined as an organized medical care given to a person, organization or even a community either by a doctor, nurse or any other licensed healthcare professional
However, healthcare-associated Infections, are those infections patients can get during their treatment for another condition due to bacteria, viruses, fungi, and other pathogens.
And for a good reason, the fundamental purpose of healthcare is to enhance healthy living and quality of life by giving quality healthcare services.
So therefore, the location which will be assessed when palpating the area in which the first primary teeth will erupt is the lower central incisors; then, followed by the upper central incisors
