  1. A data set shows five stores' monthly costs: $12K, $15K, $9K, $18K, $11K. An analyst removes the highest-cost store from the analysis. What is the new average?

    Answer: $11,750

    Removing $18K: remaining stores sum = 12+15+9+11 = 47; 47/4 = $11,750.

  2. A line graph shows a company's stock price over 6 months. The price was $50 in Month 1 and $65 in Month 6, with no clear straight-line trend between. Which statement is most accurate?

    Answer: The net change was +$15 but intra-period volatility is unknown from this info

    Only endpoint values are stated; intra-period movements cannot be determined from two data points alone.

  3. A table compares two investment options: Option A returns 8% annually on $10,000; Option B returns 6% annually on $15,000. After one year, which yields more absolute return?

    Answer: Option B with $900

    Option A: 8%×$10,000=$800; Option B: 6%×$15,000=$900, so Option B yields more.

  4. A chart shows that 3 out of every 8 employees work remotely. In a company of 480 employees, how many work on-site?

    Answer: 300

    Remote workers = (3/8)×480=180; on-site = 480−180 = 300.

  5. A grouped bar chart shows male and female scores on two tests. On Test 1, males averaged 72 and females averaged 78. On Test 2, males averaged 85 and females averaged 80. Which conclusion is supported by this data?

    Answer: Males improved more between tests

    Males improved 13 points (72→85) while females improved only 2 points (78→80), so males improved more.

  6. A cumulative frequency table shows that 80 out of 200 respondents prefer Brand X. A later survey of 500 people shows 175 prefer Brand X. Has the preference rate increased, decreased, or stayed the same?

    Answer: Decreased from 40% to 35%

    First survey: 80/200=40%; second survey: 175/500=35%; the preference rate decreased.

  7. An analyst says 'sales doubled last quarter.' A bar chart shows Q3=$1.2M and Q4=$2.1M. Is the analyst's claim accurate?

    Answer: No, sales increased by 75%, not 100%

    Doubling would require Q4=$2.4M; actual growth = (2.1−1.2)/1.2 = 75%, not 100%.
