某商场家电销售部有营业员20名，为了调动营业员的积极性，决定实行目标管理，即确定一个月的销售额目标，根据目标完成情况对营业员进行适当的奖惩．为此，商场统计了这20名营业员在某月的销售额，数据如下：（单位：万元）
（3）如果将众数作为月销售额目标，能否让至少一半的营业员都能达到目标？答：______．（填“能”或“不能”，不说理由） |
（1）
| 销售额（万元） | 17 | 19 | 20 | 21 | 25 | 26 | 28 | 30 |
| 频数（人数） | 1 | 1 | 3 | 3 | 3 | 5 | 2 | 2 |
先将20个人的销售额相加可得其和为480，所以平均数为
=24；480 20
（3）不能
因为此时众数26万元＞中位数25万元
（或：因为从统计表中可知20名营业员中，只有9名达到或超过目标，不到半数）

I feared making mistakes, and the added pressure caused me to make more than my usual 14 . Is all this pressure necessary? I 15 up leaving the football team. Four other girls did the same, and two of them stopped playing football completely. That's 16 , because they had so much potential.
