The sample size is
The mean is
The standard deviation is
Given that the confidence level is 95% then the level of significance is mathematically represented as
=>
=>
Next we obtain the critical value of from the normal distribution table , the value is
Generally the margin of error is mathematically represented as
substituting values
The 95% level of confidence interval is mathematically represented as
substituting values
The 95% level of confidence mean that there is 95% chance that the true population mean will be in this interval
