If it was typo and the original equation is 3x^2 - 10x - 8, then the answer would be (<span><span>3x+2)(x-4), but if not then IDK.
Hope this helps!</span></span>

Answer:
And we are 9% confidence that the true mean for the difference of the population means is given by:
Step-by-step explanation:
For this problem we have the following data given:
represent the sample mean for one of the departments
represent the sample mean for the other department
represent the sample size for the first group
represent the sample size for the second group
represent the deviation for the first group
represent the deviation for the second group
Confidence interval
The confidence interval for the difference in the true means is given by:
The confidence given is 95% or 9.5, then the significance level is 
and 
. The degrees of freedom are given by:
And the critical value for this case is 
And replacing we got:
And we are 9% confidence that the true mean for the difference of the population means is given by:
<span>-12/16 </span><span>< </span><span>3/4 </span><span>= </span><span>9/12 </span><span>< </span><span>2 </span><span>< </span><span>3 5/8</span>
