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:

There are 252.07 grams of ammonium dichromate per mol of ammonium dichromate molecules. There are 8 atoms of hydrogen per molecule of ammonium dichromate.
Convert grams to mole of molecules. And then molecules to atoms.
55.90 / 252.07 = moles of molecules
Since there are 8 hydrogen per 1 molecule multiply this by 8.
55.90 * 8 / 252.07 = 1.77 moles of hydrogen
