95% confidence interval is BETTER than 90% confidence interval
Step-by-step explanation:
95% Confidence Interval means that in the given data set, 95% of the time (after repeated sample experiments), the data set contains the population mean. 90% confidence interval means that 90% of the time, the data set contain the mean.
Therefore a 95% confidence interval gives a higher fidelity/precision with the data statistics than 90% confidence interval.
