Answer:
D. No, because 50% is within the bounds of the confidence interval.
Step-by-step explanation:
"52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus±3%"
This means that the 95% confidence interval for the percentage of people that plan on voting for Robert Smith is
(52-3 = 49%, 52+3 = 55%).
We can't say that he will win the election, because at the 95% confidence level, the proportion is not guaranteed to be above 50%.
So the correct answer is:
D. No, because 50% is within the bounds of the confidence interval.

Answer:
$760
Step-by-step explanation:
The number of adult ticket is the same as the number of (age 5-12) tickets.
Let the number of adult ticket be x
Number of (age 5-12) tickets be x
Total ticket sold = 38
x + x = 38
2x = 38
x = 19
Cost of each adult ticket = $23
Total cost for 19 such tickets = 23×19
= $437
Cost of each (age 5-12) ticket = $17
Total cost for 19 such tickets = 19×17
= $323
Total cost of 38 tickets = 437 + 323
= $760
Hence, the total cost of tickets is $760
