Answer:
Step-by-step explanation:
Given that many couples believe that it is getting too expensive to host an "average" wedding in the United States.
Population mean =24066
Sample mean = 23224
Sample size = 40
Sample std dev = 2903
Since sample std dev is known, we use t critical value.
df =39
Sample mean follows a normal distribution with mean = 23224, and std dev = ![\frac{s}{\sqrt{n} } \\=\frac{2903}{\sqrt{40} } \\=459.005](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D%20%5C%5C%3D%5Cfrac%7B2903%7D%7B%5Csqrt%7B40%7D%20%7D%20%5C%5C%3D459.005)
t critical value = 2.023
Margin of error = 2.023*459.005
Confidence interval![(22295.43, 24152.57)](https://tex.z-dn.net/?f=%2822295.43%2C%2024152.57%29)
The last answer is correct.

Answer:
25.2
Step-by-step explanation:
A calculator will evaluate this for you. If you don't have one, you can use a Google search box.
The Order of Operations tells you to start evaluation with the inner parentheses. Multiplication is performed before addition.
2(7 +2(2.8))
= 2(7 +5.6)
= 2(12.6)
= 25.2
