In this study we have performed two tests. The first is if the average TiQ is lower than the market
or if more resources should be allocated.
The second test was to assess whether the new protocol is better than the traditional one. For
both tests we carry out the four necessary steps. These are:
1) Determine the null hypothesis and the alternative hypothesis
2) Determine the significance level
3) Determine the critic Z-value
4) Conclusion
For the first case the steps are:
Avg Qit = 160.89
Dev Std = 159.88
N = 1674
1) H0: Avg QiT = 150
H1: Avg Qit > 150
2) α= 1.64
3) Z= ((Avg QitT - AvG H0 ) / Dev / sqr(N))
Z= (160.89 150) / 159.88/(1674^0.5)
Z= 2.78
4) Conclusion: With a 95% of confidence we reject the null hiphotesis that the QiT is 150
seconds
So, we can see that we should allocate more resources to improve de average QiT
