A jet plane can carry up to 200,000 liters of fuel. It used 130,000 liters of fuel during a flight. What percentage of the fuel
-Dominant- [34]

Given:

Capacity of jet plane = 200,000 liters of fuel

Fuel used during flight = 130,000 liters

To find:

The percentage of the fuel capacity it uses on this flight.

Solution:

According to the question, we need to find 130,000 is what percent of 200,000.

\text{Required percentage}=\dfrac{\text{Fuel used during flight}}{\text{Capacity of jet plane}}\times 100

\text{Required percentage}=\dfrac{130000}{200000}\times 100

\text{Required percentage}=65

Therefore, the jet plane uses 65 percent of fuel capacity during flight.

The average age in a sample of 190 students at City College is 22. As a result of this sample, it can be concluded that the aver
m_a_m_a [10]

Answer:

The true mean \mu it probably could be larger, smaller, or equal to 22

Step-by-step explanation:

False.

By definition the sample mean is defined as:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

For this case the value for the sample size is n =190 and the calculated sample mean is \bar X=22. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean \mu since we probably have variability from the data of the students at City College.

So we can conclude that the true mean \mu it probably could be larger, smaller, or equal to 22
