­2. Which of the following can be properly inferred about the number of Optical SFP Transceiver units sold by the four companies in 2017?Pacific Communications had the lowest standard deviation for the four quarterly figures.Pacific Communications had the greatest range for the four quarterly figures.Pacific Communications sold the largest number of units in 2017.Light Speed Technologies sold the largest number of units in any individual quarter.No company sold less than 25,000 units in any individual quarter.


A. Pacific Communications had the lowest standard deviation for the four quarterly figures.
TRUE, since all sales figues in the range of 36k-38k (apprximating the mean), while there is large variation in the sales figures of the remaining 3 companies.

B. Pacific Communications had the greatest range for the four quarterly figures.
FALSE, since Silicon Labs had the greatest range.

C. Pacific Communications sold the largest number of units in 2017.
FALSE, since Light Speed Technologies sold the largest number of units in 2017.

D. Light Speed Technologies sold the largest number of units in any individual quarter.
FALSE, since Silicon Labs sold the largest number of units in any individual quarter ie, in Q1 of 2017.

E. No company sold less than 25,000 units in any individual quarter.
FALSE, since Starcom sold less than 25,000 units in any individual quarter ie, in Q4 of 2017.


IMO, (A) will be the correct answer

Can Somebody please explain the answer choices for Q2 and Q3, For Q2 how is it that Pacific has the lowest SD ? and for Q3 (2nd question) how the price per unit is calculated, i mean we are given the revenue for 2017 and then respective units produced and then % of those units sold. So the Revenue = price per item x no. of units sold. Aren't we going to calculate highest or lowest price per unit by considering the no. of units sold for all of the quarters, this is so confusing 😕

For Q2 we are given the amount of units produced and also the percent sold. The question is asking for the company with the lowest standard deviation among the amount of units sold.

Pacific produces: 42,185 - 45265 - 39,456 - 58,235
Pacific sells: ------- 92% -- 85% --- 98% ---- 62%

If we take the percent sold from the total produced: 42,185(.92), 45,265(.85), 39,456(.98), 58235(.62)

We get: 38810, 38475, 38666, 36105 Units sold, which is the lowest standard deviation.

1. At least one of the companies for which data is provided had excess inventory at the end of 2016.
-This question is a trap because we are not given any data on 2016 and exclusively 2017; so the answer is NO

2. Among the four companies, Starcom had the highest average price per unit in 2017.
-Based on the tables, Starcom consistently produces a lower amount of items and also sells a lower percentage of produced items. However, they have the second highest revenue meaning they must charge significantly more than other companies. Therefore the answer is YES.

3. None of the four companies sold more units in the fourth quarter of 2017 than they did in any other individual quarter of 2017.
-To solve this you need to take the sales percentage of the production data to calculate the number of units sold. The question is asking us to identify a company that sold the most amount of units in it's fourth quarter. Since a lot of percentages are ~100%, it's a quick comparison between quarters, and the only number I would calculate is the Light Speed Technologies quarter 3 and quarter 4, as it's close and is what gives our answer. Because of the way the question's phrased, since LST had a higher quarter 4 than any other quarter, the answer is NO.

Q3 part 1 is no since it says 2016 and not 2017 - no calculation needed

I personally found it easier to just eliminate answer choices rather than solving for just one. Some of the options can be eliminated almost immediately (E) and the others only took like 30 seconds to prove false (B,C,D).
