Assuming the population of interest is approximately normally distributed, construct a 95% confidence interval estimate for the population mean given the values below. x overbar=19.3 s=3.1 n=23 the 95% confidence interval for the population mean is from nothing to nothing.

Step-by-step explanation:

The confidence interval for population mean is given by :-

Given :

n=23, which is a small sample(n<30), so we use t-test.

Significance level:

Critical value :

Then , the  confidence interval for population mean will be  :-

Hence, the 95% confidence interval for the population mean is

answer: do we write it
