“Extraneous solutions are not solutions at all. They arise from outside the problem, from the method of solution. They are extraneous because they are not solutions of the original problem. ... To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.”
Basically, they are an answer you get when you solve a problem, but they don’t actually make the equation true so you disregard it.
From what I remember, hear is an example cuz idk how to really explain... there are 3 yellow cubes, 4 green, and 2 blue cubes all in one bag. You add the total number of cubes (3+4+2=9) let’s say I want to know what is the probability of grabbing a yellow cube. There is a total of 3 yellow cubes in the bag so just put that over 9 in a fraction (3/9) so that would be your fraction probability and if you want a percentage you just divide the numerator (3) by the denominator (9) which would be .33 so there is a 33% chance of grabbing a yellow cube. I’m so sorry if this didn’t help x-x
Answer:
There is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 610
p = 23.8% = 0.238
Alpha, α = 0.01
Number of 18-24 year-old attending college , x = 178
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.0009
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.
Conclusion:
Thus there is enough evidence to support the claim that the percentage of residents attending college in that age-group is greater than 23.8%
