3.3 Statistical analysis results for the third experiment.
Graph 1.1 shows the linear fit, the proportionality between pressure and volume. This plot
gave us the relationship between pressure and volume: P=mV (m being the slope).
Table 1.2 shows the experimental values of the pressure and volume. The table also shows the
k values calculated using the information obtained in graph 1.1 (we notice that the k values
are close to each other).
Table 1.3 shows the statistical analysis. The statistical analysis calculations allow us to know
if the m is statistically equal to the k values calculated. The calculation that really allows
proving it is the confidence interval (CI).
For this first experiment, m is not in the confidence
interval so m and k can’t be considered statistically the same.
Graph 2.1 also shows the linear fit, but this time between pressure and temperature. This plot
also gave us the relationship between pressure and temperature: P=mT (m being the slope).
Table 2.2 shows the experimental values of the pressure and temperature. The table also
shows the k values calculated using the information obtained in graph 2.1(we notice that the k
values are also close to each other).
Table 2.3 shows the statistical analysis for the second experiment. The objective of these is
the same as for the first experiment. For this experiment, m is also in the confidence interval;
m is then considered statistically the same as the k values calculated.
Graph 3.1 shows the linear fit between the volume and temperature. This plot gave us the
relationship: V=mT (m being the slope).
Table 3.2 shows the experimental values of the volume and temperature. The last column
shows the k values calculated using the information obtained in the graph 3.1.
Table 3.3 shows the statistical analysis for the third experiment. The objective of these is the
same as for the first in second experiments. For this experiment, as the previous experiment,
m is in the confidence interval; m is then considered statistically the same as the k values
calculated.

DISCUSSION:
The main objective of this experiment was to confirm the three hypotheses stated at the
beginning of the experiment. The three hypotheses were stated were:
