Table 4: Results of the operation range of the operator 1 per day.
In the figure 4 is shown the correlation between temperature and strength in the 7 days, being r -
0.072. As r is -0.072 and 0.119 which is lower than the critical value we conclude that H0 is not
rejected as there is insufficient evidence to conclude that there is a significant linear correlation.
Figure 4: Correlation between Temperature (°C) and
Strength (Kg) of the operator 2 in the 7days.
In the figure 5 is shown the correlation between cycles per minute and temperature in the 7 days,
with r -0.172. As r is -0.172 and its absolute value is 0.172 and 0.119 which is greater than the
critical value we conclude that there is a significant linear correlation, and H0 is rejected.
