Answer: increased
Step-by-step explanation:
- An x% confidence interval indicates that a person can be x% confident that true population parameter lies in it.
More level of confidence more width of the interval.
As level of Confidence interval increases width of interval increases.
 Width of interval  level of Confidence interval
  level of Confidence interval
So, If a 95% confidence interval had been constructed instead of 90% the width of the interval would have been<u> increased.</u>
 
        
             
        
        
        
Answer:
Area of the parallelogram is 96  .
.
Step-by-step explanation:
A parallelogram is a quadrilateral with parallel and equal length of opposite sides. The diagonals are perpendicular to each other.
Area of a parallelogram is given as,
Area = base x height
Thus for the given parallelogram with base 12 cm and height 8 cm, the area would be;
Area = base x height
         = 12 x 8
         = 96
Area = 96 
The area of the parallelogram is 96  .

Answer:
Step-by-step explanation:
Given that two fair dice are rolled 3 times and the sum of the numbers that come up is recorded.
a) The sum is 4 on each of the three rolls.
(1,3) (2,2) (3,1) HEnce for one throw prob = 3/36 =1/12
Prob for getting same sum 4 in 3 rolls = 
(since each trial is independent)
b) Prob sum =4 in exactly 2 rolls
=  =
=
