Hi
ME =1.96[34.7/sqrt(50)] = 9.618		
CI: 167.4-9.618 &lt; u &lt; 167.4 + 9.618		
CI: 157.78 &lt; u &lt; 177.02		

ME =1.96[34.7/sqrt(5)] = 30.416
 CI: 136.98 &lt; u &lt; 197.82
confidence intervals in problems 4 and 6 are differ due to sample size
the smaller the sample, the larger the interval is
