Researchers are interested in estimating the prevalence of hypertension in a population of adults aged 40-65 from a particular community.Suppose the national prevalence in this population is 40% (p=0.40). The research team has enrolled n=180 participants.

The expected number ofhypertensive adults in this sample, rounded to the nearest integer =.

The expectednumber ofadults in this sample who are nothypertensive=.

Can the distribution of hypertensive adults be approximated by the normal distribution, given this sample? (yes or no)
