In 1999, nearly all households in Country X purchased salty snacks. About 91% of households bought potato chips, purchasing an average of 9.8 pounds and spending roughly $26 over the year. A broader category—all chips (including potato, corn, and tortilla)—was purchased by 95.5% of households, with average annual purchases of 16.3 pounds. Other salty snacks, such as pretzels, cheese puffs, microwave popcorn, and packaged or bulk nuts, were purchased by 96.8% of households.
Considering all salty snacks, 99.2% of households made purchases in 1999. Among those who did, the average household bought 31.8 pounds and spent approximately $76.40. On a per-person basis, the average quantity purchased was 14.5 pounds.
Three key points emerge:
• Salty snack consumption was nearly universal, so almost all households would have been affected by a per-pound tax.
• Purchase quantities and spending varied systematically by household characteristics and demographics.
• Despite this variation, salty snacks represented a relatively small portion of household spending.

Official Solution:
• Each household that purchased salty snacks in 1999 purchased more than 1 pound.
The histogram shows that some households fall into the 0–2 pound range. While we don’t know the exact breakdown within that bar, it's entirely possible that some households purchased 1 pound or less. Not supported.
• Approximately one-fifth of all households consumed 10 pounds or fewer of salty snacks in 1999.
The bars covering 0–10 pounds (from the first to the sixth bars) collectively account for close to 20% of all households, based on the percentages shown in the histogram. Supported.
• The median range of salty snack consumption is approximately 70 pounds greater than the modal range of salty snack consumption.
As stated in Tab 2, the modal range is 10–12 pounds. The median represents the midpoint of the distribution—where 50% of households purchased less and 50% purchased more. A median that is approximately 70 pounds higher than the modal range would place the median around 80 pounds, which would mean that 50% of households purchased less than 80 pounds and 50% more than 80 pounds. This is clearly incorrect, as the graph shows that far fewer households purchased more than 80 pounds than purchased less. Not supported.
