Many rules govern drivers on American streets and highways. The most common ones are the speed limits(限制). The speed limits control how fast a car may go.

On streets in the city,  the speed limitis usually 25 or 35 miles per hour.On the highways between cities, the speedlimit is usually 55 miles per hour. When people drive faster than the speedlimit, a policeman can stop them. The policemen give them pieces of paper which people call traffic tickets. Traffic tickets tell the drivers how much money they must pay. When drivers receive too many tickets, they probably cannot drive for a while. 

The rush hour is when people are going to work or going home from work. At rush hour there are many cars on the streets and traffic moves very slowly. Nearly all American cities have rush hours. Drivers do not get tickets very often for speeding during the rush hours because they cannot drive fast.

如果25×4=100，那么，____是____的因数，____也是____的因数；____是____的倍数，____也是____的倍数。

（Ⅰ）以样本估计总体，视样本频率为概率，在小明 $QQ$ 朋友圈里的男性好友中任意选取3名，其中走路步数低于7500步的有 $X$ 名，求 $X$ 的分布列和数学期望；

（Ⅱ）如果某人一天的走路步数超过7500步，此人将被“ $QQ$ 运动”评定为“积极型”，否则为“消极型”.根据题意完成下面的 $2\times 2$ 列联表，并据此判断能否有 $95\%$ 以上的把握认为“评定类型”与“性别”有关？
