Parenthesis first, (4*8)= 32 * 7n = 224n
        
                    
             
        
        
        
Answer:
Height=9/2=4.5
A=1/2*b*h
A=1/2*6*4.5
A=13.5
13.5*2=27
The area of the shaded region is 27.
 
        
             
        
        
        
Answer:
Interval is given with 97% confidence. Thus there is 3% probability that interval is not true. 
Step-by-step explanation:
In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence. 
<em>Statistically</em>, this means that the person can be 97% sure (not 100%)  that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval. 
Small sample size may also lead wrong estimates. 
 
        
             
        
        
        
Answer:200,000

I don't know the effect, but I can tell you the outlier, mean, and the median.
Outlier: 60
Mean: 87.8
Median: 60
