from a population are called
95%
DONE
The mean and the standard deviation of a normal population are called parameters, and of a random sample from a population are called statistic
Normally distributed data
In a normal distribution, data is symmetrically distributed with no skew
Normally distributed data is the distribution of probability which is symmetric about the mean.
Normal distributions are symmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal
How to solve this problem?
The steps are as follow:
The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the dataset.
Those numbers who summarize information about sample are called statistic.
The numbers which summarize information about population are called parameters.
The numbers which summarize information about the sample are called statistic.
Therefore, the mean and the standard deviation of a normal population are called parameters, and of a random sample from a population are called statistic
