Answer :
True, The normalized normal distribution is used to calculate population percent confidence intervals regardless of whether the population standard deviation is known.
The mean-bell-shaped curve is one of the most frequent continuous random variables.
A normal distribution's mean is fully symmetrical. The sampling rate is used to calculate the percentage population confidence interval.
The z-distribution, often known as the standard normal distribution, is a form of normally distributed with mean 0 and variance 1.
A transform can be used to normalize the values of a normal distribution. It is subsequently transformed into a z value.
The amount of standard variations between each result and the mean is represented by the Z-score.
Normalized distributions are used to construct confidence intervals for population percentages when the sample size is big enough.
