If a sample of 35 employees had been selected, could we find a 95% confidence interval for the average salary of the entire company? O Yes because when I plug 35 into the calculator with the previous average of $55,000 and standard deviation of $5,000 I get a confidence interval of ($53,343.53, $56,656.47) No since 35 is less than 40.
