Suppose that when a signal having value & is transmitted from

Suppose that when a signal having value & is transmitted from location A the value received at location B is normally distributed with mean / and variance o'. To reduce error, suppose the same value is sent 9 times. If the successive values received are 5, 8.5, 12, 15, 7, 9, 7.5, 6.5, 10.5, compute a 95 % confidence interval for / when 0' =4 is unknown
