A network administrator should implement one-way NAT when the network has a limited number of public IP addresses and numerous private IP addresses that require external access.

One-way NAT (Network Address Translation) is implemented by a network administrator when there is a scarcity of public IP addresses and a large number of private IP addresses within the network that need to access external resources.

With one-way NAT, the private IP addresses are translated to a single public IP address when outbound traffic flows from the internal network to the external network. This allows multiple internal hosts to share a single public IP address, optimizing address utilization while still enabling communication with external resources.

The translation process is typically configured in the network gateway or router, which performs the necessary address translation to facilitate outbound communication.

The percentage of data that falls outside 2 standard deviations of the mean is approximately 4.55%.

In statistics, the concept of standard deviation measures the spread or dispersion of data around the mean. By definition, approximately 68% of the data falls within one standard deviation of the mean in a normal distribution. When considering two standard deviations, this coverage increases to about 95%. Consequently, the percentage of data falling outside two standard deviations is calculated by subtracting 95% from 100%. Hence, the remaining 5% represents the proportion of data that falls beyond two standard deviations.

Since the normal distribution is symmetric, the proportion of data that falls beyond two standard deviations is divided equally into the left and right tails of the distribution, making each tail approximately 2.5%. When combined, the percentage of data falling outside 2 standard deviations of the mean is approximately 4.55%.

In part 1, you made two claims: a) that the patient has bacterial meningitis and b) that the patient has viral meningitis. Multiplex PCR is a technique that allows for the simultaneous detection of multiple pathogens in a single sample, so it is possible that both bacterial and viral pathogens are present in the patient's cerebrospinal fluid (CSF).

The multiplex PCR results may also support either of your claims, depending on which pathogens were detected. If bacterial DNA was detected, then this would support your original claim of bacterial meningitis. If viral DNA was detected, then this would support your alternative claim of viral meningitis.

However, it is also possible that the multiplex PCR results are inconclusive or do not detect any pathogens in the patient's CSF. In this case, further testing and evaluation would be necessary to make a definitive diagnosis.

It is important to note that diagnostic testing, including multiplex PCR, should always be interpreted in the context of the patient's clinical presentation and other laboratory findings. A diagnosis of meningitis should not be based solely on the results of a single test, but rather on a combination of clinical and laboratory data.

Increasing the sample size tends to decrease the margin of error, e, in statistical inference.

In statistical inference, the margin of error (e) quantifies the uncertainty or variability in estimating population parameters based on a sample. It represents the range within which the true population parameter is likely to fall. The margin of error is typically expressed as a plus or minus value around a point estimate, such as a mean or proportion.

When the sample size is increased, the margin of error tends to decrease. This is because a larger sample size provides more information about the population, resulting in a more precise estimate of the population parameter. As more data points are collected, the variability and uncertainty associated with the estimation process decrease. Consequently, the confidence interval, which is determined by the margin of error, becomes narrower.
