A point estimate is an estimate where a     a. sample statistic is used to estimate the exact value of a population parameter.     b. sample statistic is used to estimate a range of possible values of a population parameter.     c. population parameter is used to estimate the exact value of a sample statistic population.     d. parameter is used to estimate a range of possible values of a sample statistic.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
