Answer:
0.17 or 17 percent
Step-by-step explanation:
You go the graph where it says urban (the question states among the urabn population and add all of the numbers together to get 126, and you go to the two year degree column (it is looking for the two year degrees from this column) and you divide that number (21) by your sum earlier to get 0.16666667 and round it up to 0.17 which is 27 percent if you want a percentage as an answer.
The answer is 2/5.
There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.
Answer:
0.7611 = 76.11% probability that the weight of a randomly selected steer is less than 1140lbs.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
![\mu = 900, \sigma = 300](https://tex.z-dn.net/?f=%5Cmu%20%3D%20900%2C%20%5Csigma%20%3D%20300)
Find the probability that the weight of a randomly selected steer is less than 1140lbs.
This is the pvalue of Z when X = 1140. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \frac{1140 - 900}{300}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B1140%20-%20900%7D%7B300%7D)
![Z = 0.71](https://tex.z-dn.net/?f=Z%20%3D%200.71)
has a pvalue of 0.7611
0.7611 = 76.11% probability that the weight of a randomly selected steer is less than 1140lbs.
