Final answer:
To determine the weight at the 68th percentile for the weights of steers using model N(1124, 60), one must find the z-score for the 68th percentile and then calculate the weight using the mean and standard deviation. Exact calculations are necessary to provide a specific answer.
Step-by-step explanation:
To find the weight that represents the 68th percentile for the weights of steers using the Normal model N(1124, 60), we need to determine the z-score that corresponds to the 68th percentile and then use the standard deviation and the mean to find the actual weight.
The z-score can be found using a standard normal distribution table or a calculator with statistics capabilities.
Once we have the z-score, we use the formula:
Weight = Mean + (Z-score × Standard Deviation)
Unfortunately, without the specific z-score, we are unable to answer this question definitively.
Normally, the 68th percentile would be slightly below the mean in a standard normal distribution, as 68% is often associated with the range of one standard deviation from the mean, but exact calculations would be required to find the specific weight.
