Document Summary

Weeks t 4 weeks 5 9 t 2. Mean median and mode are equal to each other her. The z distribution always has mean and standard deviation l. 2 in course outline but shown anyways to the. The column gives the value of second decimal point. The row shows the value of 2 to decimal point. The value within the table gives the probability from e. A distribution of all of the possible value of a sample statistic. Whenprobability roughly is in each group the same number. The mean and std dev sampling distribution of a is also normally distributed normal the. T 2 fn the population is not normal. Even if sample means from the population will be approximately normal as long as thesample size. If n 230 distribution is large enough we wil have a nearly normal sampling point and interval estimates. A confidence interval provides additional the estimate about the variability of information tower confidence.
