Luden [163]
<span><u><em>Answer:</em></u>
Kevin made $800 in commissions last week.

<u><em>Explanation:</em></u>
Since we know that he only makes money in two ways, by base salary and commission, we know that added together they equal his whole pay.

<u>Therefore we can set up the following equation and solve for his commission amount. </u>
Total Pay = Base Pay + Commissions.
1125 = 325 + Commissions.
800 = Comissions. </span>

Find the​ range, variance, and standard deviation for the given sample data. Include appropriate units in the results.Listed bel
timama [110]

Answer:

D.​No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Step-by-step explanation:

(a) Range is the difference between the smallest and largest observation.

Here Smallest observation = 0.63

and Largest observation = 1.48

⇒ Range = 0.85

(b) Standard Deviation is calculate by,

Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }

where, \bar{x} is mean of the observation.

Here, Mean = 0.988

⇒ Standard Deviation = 0.313

(c) Variance is the square of Standard deviation.

Thus, Variance = (Standard Deviation)² = 0.098

(d) Here last option(D) is true i.e. ​No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.
