A hot air balloon has a volume of 15 L when it’s released from sea level, where the pressure is 100 kPa. What will be the hot ai
Lunna [17]

Answer:

65 L

Explanation:

It is assumed that the temperature is constant at both the sea level and the altitude.

<em>According to the gas law, at constant temperature, the pressure of a gas is inversely proportional to its volume.</em> Mathematically:

P1V1 = P2V2 where P1 = pressure at initial volume, V1 = volume at initial pressure, P2 = pressure at final volume, and V2 = volume at final pressure.

In the illustration, V1 = 15 L, P1 = 100 kPa, V2 =?, P2 = 23 kPa

V2 = P1V1/P2 =  100 x 15/23 = 65.22 L

<u>The volume of the hot air balloon at the altitude would be 65 L</u>

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).  

The inference procedure uses the information collected from the sample in order to obtain one conclusion.  Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
