Use the Normal model
N(1110,70) for the weights of steers.
a) What weight represents the 58th percentile?
b) What weight represents the 91st percentile?
c) What's the IQR of the weights of these steers?
The 58th percentile is 1124.1 pounds
The weight representing the 91st percentile is 1203.9, I need to find the IQR for the weights of the steers is how many lbs?
