A theory is a well tested explanation that can be replicated. A hypothesis is just an educated guess that can be proven or falsified. And a law is something that can be universalized (universal).

If the wait time is less than 30 minutes for 75% of all patients in the emergency room, what is the probability that the
Greeley [361]

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 \mathbf{\hat p} can be computed by using the expression:

\mathbf{\hat p = \dfrac{x}{n}}

\mathbf{\hat p = \dfrac{32}{55}}

\mathbf{\hat p =0.582}

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:

\mathbf{( \hat P \leq 0.582) = P \Big( \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}} \leq \dfrac{0.582 - 0.75}{\sqrt{\dfrac{0.75(1-0.75)}{55}}} \Big )}

\mathbf{( \hat P \leq 0.582 )= P \Big( Z \leq \dfrac{-0.168}{\sqrt{0.003409}} \Big )}

\mathbf{( \hat P \leq 0.582) = P \Big( Z \leq -2.88 \Big )}

From the Z distribution table:

\mathbf{( \hat P \leq 0.582) = 0.00198}

\mathbf{( \hat P \leq 0.582) \simeq 0.0020}

What is the purpose of data encryption algorithm?
Over [174]

Answer:

security/protection

Explanation:

The main purpose of a data encryption algorithm is security/protection. These algorithms grab data and change it into indecipherable code. This code can only be decrypted using a key that has been uniquely created for that exact piece of data. Usually, when the encrypted data and key have been created the key is given to the select few that need to have access to the data. This process helps protect the data from being seen or manipulated by unwanted parties.

Tate and Anna have two children who need orthodontic treatment of braces and retainers, which insurance should they purchase?
madreJ [45]
I think the insurance that they should purchase is: C. supplemental insurance

Dental insurance is not covered by Medicare, so both HMO and  Point of service is out of the option.
I think supplemental insurance will be the best option because it is the type of insurance sold by private companies that specifically cover the policies that are not covered by normal Medicare.
