The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020
<h3>What is probability? </h3>
Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.
From the parameters given:
- The sample size (n) = 55 patients
- Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients
The sample proportion
can be computed by using the expression:



If the percentage of the probability of all patients in the emergency room = 0.75
The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:



From the Z distribution table:

Traits are each complex part of our personality. Everyone's unique personality is created by specific traits that have either been picked up over time or even genetically given. Factor analysis can measure your traits by identifying-using tests- your person's basic components of intelligence. Your answers get analyzed and extraversion/ emotionality factors will emerge as your basic personality dimensions. Eysenck believed that biological factors- like arousal, hormones, and environment- affect your personality dimension.
