Answer:N/B The amount is in thousands
The total amount earned by a Bachelor's person be $x:
amount earned by a masters person will be $(2x-38)
Total amount earned by the two individuals will be:
x+(2x-38)=115
solving for x we get:
x+2x-38=115
3x=115+38
3x=153
x=153/3
x=51
also:
2x-38=2*51-38=64
therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.

Answer:
d. There is a 98% chance that the true proportion of customers who click on ads on their smartphones is between 0.56 and 0.62.
Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
I suppose(due to the options) there was a small typing mistake, and we have a 98% confidence interval between 0.56 and 0.62.
Interpreation: We are 98% sure, or there is a 98% chance, that the true population proportion of customers who click on ads on their smartphones is between 0.56 and 0.62. Option d.
True, because it is x is greater than OR EQUAL TO 4 so that means 4 is included. Then x is less than 8 so it’s not including 8. x could be 4,5,6, or 7
