JulsSmile [24]

Answer:

NO

Step-by-step explanation:

The changeability of a sampling distribution is measured by its variance or its standard deviation. The changeability of a sampling distribution depends on three factors:

  1. N: The number of observations in the population.
  2. n: The number of observations in the sample.
  3. The way that the random sample is chosen.

We know the following about the sampling distribution of the mean. The mean of the sampling distribution (μ_x) is equal to the mean of the population (μ). And the standard error of the sampling distribution (σ_x) is determined by the standard deviation of the population (σ), the population size (N), and the sample size (n). That is

μ_x=p

σ_x== [ σ / sqrt(n) ] * sqrt[ (N - n ) / (N - 1) ]

In the standard error formula, the factor sqrt[ (N - n ) / (N - 1) ] is called the finite population correction. When the population size is very large relative to the sample size, the finite population correction is approximately equal to one; and the standard error formula can be approximated by:

σ_x = σ / sqrt(n).

Einstein Office Equipment has a rental plan for office machines. A fax machine that lists for $722.98 can be rented for 22% of t
Archy [21]

Answer:

$13.68


Step-by-step explanation:

Assuming they rent for 1 year, the cost is broken down as follows:


Annual renting cost = 22% of 722.98 = \frac{22}{100}*722.98=0.22*722.98=159.06


Usage charge = 3.2% of 159.06 = \frac{3.2}{100}*159.06=0.032*159.06=5.09

Thus,

Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15


Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):

\frac{164.15}{12}=13.68 dollars
