Answer:
d. The administrators are unable to tell if there is a true difference between Oklahoma and non-Oklahoma residents in their excitement to go home for the holidays because their interval covers 0.
Step-by-step explanation:
The confidence interval refers to a rabje of statistically calculated values used in establishing a certain level of confidence in the outcome of a data.
The confidence interval is calculated thus :
Mean ± (Zcritical * Error)
The ± sign ensures we have the lower and upper boundary of our confidence level.
From the confidence level given in the question : -1.78 to 3.27
Since 0 is contained in the confidence interval range given, then it can be concluded that the difference in excitement between Oklahoma and non oklahoma residents cannot be adequately established.
