要触发Timer事件,必须通过以下( )属性。 A: Enabled、Interval B: Visible、Interval C: Enabled、Visible D: Tag、Interval

The point estimation is to determine an interval bounded by 2 values such that the probability that the parameter value is within the interval is known.( )

For a uniformly distributed random variable, the probability of the corresponding interval is related to the length of the interval, and it is also related to the starting point of the interval.

For a uniformly distributed random variable, the probability of the corresponding interval is related to the length of the interval, and it is also related to the starting point of the interval. A: 正确 B: 错误
