Answer:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42
Step-by-step explanation:
Information given
n=1045 represent the random sample selected
X=502 represent the college graduates with a mentor
estimated proportion of college graduates with a mentor
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true proportion is higher than 0.42, the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42
585.216 would be the answer
The answer would be the 3rd one, we find this by gettign our facts, first find our y-intercept, where does the line pass through the y line, it passes through the positive 4, now lets find the slope, the slpe is the rise over run, the graph rises 4 and runs 1 to the right, so your slope will be 4 now how do you know if its a positive or a negative, well if the graph rises to the right it is a positive and if it rises to the left is a negative... This graph rises to the right so our slope is a positive... SO our equations should look like f(x)=4x+4 and our 3rd option has exactly this answer, so your answer would be the 3rd one
Hope this helps
