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.( )
举一反三
- When a range of values is used to estimate a population parameter, it is called _______. A: a point estimate B: an interval estimate C: a statistical parameter D: a range estimate
- 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.
- The estimated interval [img=47x29]1803a31cd5741d9.png[/img] is formed by a pair of interval estimators [img=15x27]1803a31cde55410.png[/img] and [img=15x27]1803a31ce748559.png[/img] so that [img=189x39]1803a31cf05b641.png[/img]. Whether the statement is correct or not that the probability of the changed parameter falling within the interval [img=47x29]1803a31cd5741d9.png[/img] is [img=43x20]1803a31d099e3ee.png[/img].

- A variable that can take on values at any point over a given interval is called _______. A: a value variable B: a continuous random variable C: a point variable D: a discrete random variable
