Question

There is a direct relationship between the chi-square and the standard normal distributions, whereby the square root of each chi-square statistic is mathematically equal to the corresponding z statistic at significance level α

True or false

Answer 1

Correct option: TRUE

Explanation: Z-scores are used in the standardization of a normal distribution and it is also known as Independent samples test. A z-score measures by how many standard deviations any value away from its mean. It represents a value's relative distance from the mean based on standard deviation. For example, a value with a z-score of 2 is 2 standard deviations above the mean in a normal distribution. So it is correct statement.
