For a population with m = 60, which of the following values for the population standard deviation would cause X = 68 to have the

trapecia [35]

Answer:

Option D) s = 1

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 69

X = 68

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Computing z-scores for different standard deviation:

$z_1 = \displaystyle\frac{68-60}{4} = 2\\\\z_2 = \displaystyle\frac{68-60}{3} = 2.667\\\\z_3= \displaystyle\frac{68-60}{2} = 4\\\\z_4 = \displaystyle\frac{68-60}{1} = 8$

The standard deviation with highest z-score gives the most extreme position in the distribution.

Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.

Option D) s = 1

<span>First year sale = 150 000 dollars,
Then it grew 8% for the second years, and 2% each year for the next 2 years.
Total growth from 2-4 years increase is 45 000 dollars
Find the growth for the year 2
=> 8% = 8/100 = 0.08
=> 150 000 x .08
=> 120 000
Thus the growth of the ABC company for the second year is 120 000, that makes it
=> 150 000 + 120 000
=> 162 000 dollars.
