Answer: 0.7257
Step-by-step explanation:
Given : The weights of steers in a herd are distributed normally.
Standard deviation : ![\sigma=300 \text{ lbs }](https://tex.z-dn.net/?f=%5Csigma%3D300%20%5Ctext%7B%20lbs%20%7D)
Let x be the weight of the randomly selected steer .
Z-score : ![\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
![z=\dfrac{920-1100}{300}=-0.6](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B920-1100%7D%7B300%7D%3D-0.6)
The the probability that the weight of a randomly selected steer is greater than 920 lbs using standardized normal distribution table :
Hence, the probability that the weight of a randomly selected steer is greater than 920lbs =0.7257
Answer:
68+72+85=225
plus 79 =304 divided by 4 = 76
plus 89 =314 divided by 4 = 78.5
plus 91=316 divided by 4 = 79
so the answer is C
