The confidence level and sample data to find a confidence interval for estimating the population mu. round your answer to the same number of decimal places as the sample mean 88.2 < μ < 93.0.
<h3>What are the confidence level?</h3>
The confidence stage refers to the proportion of probability, or certainty, that the self-belief c language could include the real populace parameter whilst you draw a random pattern many times.
- We have this given info:
- n = 92 = pattern length xbar = 90.6 = pattern imply
- sigma =8.! = populace popular deviation
- C=99% self-assurance level
- Because n > 30 and due to the fact we recognize sigma, this permits us to apply the Z distribution (aka popular ordinary distribution).
- At 99% self-assurance, the z essential price is more or less z = 2.576 use a reference sheet, table, or calculator to decide this.
- The decrease sure of the self assurance c programming language (L) is more or less L = xbar - z*sigma/sqrt(n) L = 90.6-2.576*8.9/sqrt(92) perp= 88.209757568781 perp= 88.2
- The top sure (U) of this self assurance c programming language is more or less U = xbar + z*sigma/sqrt(n) L = 88.209757568781 L = 88.2.
- The top sure (U) of this self assurance c programming language is more or less U=xbar+z^ * sigma/sqrt(n) U = 90.6 + 2.576*8.9/sqrt(92) U = 92.990242431219
- U = 93.0.
- Therefore, the self assurance c programming language withinside the format (L, U) is about (88.2, 93.zero).

Based on the information the ratio between the deficit and gdp as a percentage is 2.41%.
<h3>Ratio between the deficit and gdp:</h3>
Using this formula
Ratio between the deficit and gdp=Annual federal deficit/Gross domestic product×100
Where:
Annual federal deficit=$350 billion
Gross domestic product=$14,500 billion
Let plug in the formula
Ratio between the deficit and gdp=$350 billion/$14,500 billion×100
Ratio between the deficit and gdp=2.41%
Inconclusion the ratio between the deficit and gdp as a percentage is 2.41%.

The gas with a higher pressure is <u>Helium </u>
<h3 /><h3>Calculating the pressure exerted by the gases</h3>
Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.
<u>Pressure of </u><u>Helium </u>
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
<u>Pressure of</u><u> Ammonia </u>
P = n
where n ( number of moles ) = mass / molar mass of ammonia
= 73 / 17.03
= 4.29 moles
From the calculations above the gas with a higher pressure is Helium.
