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 of hypertensive adults in this sample, rounded to he nearest integer=
The expected number of adults in this sample who are not hypertensive =
Can the distribution of hypertensive adults be approximated by the normal distribution, given this example?
