For each of the following statements, select
True if the statement can be verified as true based on the information provided. Otherwise, select
False.
If no company had less than or equal to 1% of total national sales in Electronics, then only two companies accounted for national sales in that category. • Company Y had 49.5% of total national sales in Electronics and was ranked 2nd, meaning one other company had more than 49.5%. That leaves less than 1% of the market for any other companies combined. Since the condition states that no company had less than or equal to 1%, no third company could exist in this category. Therefore, only two companies could have accounted for national sales in Electronics.
If no company had less than or equal to 2% of total national units sold in Apparel, then at most five companies accounted for units sold in that category. • Company Y had 24% of national units sold in Apparel and was ranked 4th, meaning at least three other companies had more than or equal to 24%. Thus, these four companies accounted for more than 4 * 24% = 96%. So, less than 4% remains for any additional companies. Since no company had less than or equal to 2%, only one more company can fit into the remaining share. Therefore, at most five companies could have accounted for units sold in Apparel.
Company Y’s median rank by sales share is equal to its median rank by units sold across all product categories shown. • To compare medians, we list all ten ranks by sales share and units sold in order. Company Y’s ranks by sales share are: 1, 2, 2, 2, 2, 2, 5, 7, 9, 10. The median is the average of the 5th and 6th values: (2 + 2)/2 = 2. For units sold, the ranks are: 1, 2, 3, 4, 4, 4, 5, 8, 9, 10. The median is the average of the 5th and 6th values: (4 + 4)/2 = 4. Since the medians are not equal, the statement is false.
