Answer:

Step-by-step explanation:

A survey of 8225 Americans included age data collection.

The mean age was recorded as 42, whereas the median was noted as 37.

This indicates median < mean.

When the mean exceeds the median, it suggests the presence of right skewness in the data.

In a symmetrical distribution, mean and median align. If there is a discrepancy, the distribution is skewed.

Consequently, with the mean > median, the data is skewed to the right.

Zina [12379]

Answer:

To enhance availability by 5%, the downtime due to repairs or reboots needs to drop by 600 hours

Step-by-step explanation:

Increasing availability to 5% involves multiplying the current availability hours by 105%.

Thus, 1.05 × 12000 = 12600 hours

Consequently, the repair/reboot duration must be lessened by 600 hours.

An advertising company designs a campaign to introduce a new product to a metropolitan area of population 3 Million people. Let
PIT_PIT [12445]
Step-by-step explanation: Since the number P(t) increases proportionally to the number of individuals unaware of the product, we establish that initially, nobody is aware of the product at the campaign's start and that 50% are aware after 50 days of advertisements. Thus, we determine: P(0) = 0 and P(50) = 1,500,000, leading to a first-order ordinary differential equation. The integrating factor must be calculated and both sides of the equation manipulated accordingly. Hence, upon integrating and solving, we arrive at the equation modeling the number of people (in millions) aware of the product over time.

Answer:

What is the variation for each successive input?

✔ 1

What is the variation for each successive output?

✔ 0.35

What is the rate of variation for the correlation?

✔ 0.35

Step-by-step explanation:

The change per input is 1 since the inputs are 10,11,12,13.

The change for each successive output is 0.35 because we must subtract 4.1 from 3.75.

Thus, the rate of variation for the correlation is likewise 0.35.

Answer:

In this case, the method of sampling employed by the poll

Explanation:

Convenience sampling, often referred to as grab, opportunity, or accidental sampling, is a non-probability sampling technique where the sample is collected from the part of the population that is easily accessible. This technique proves to be particularly useful for preliminary investigations.

This type of sampling makes selections based on ease of access, willingness of individuals to participate, and availability at specific times.

Consequently, this approach can lead to biased results and may not yield the expected outcomes.
