Answer:
Given confidence interval is 0.54+or-0.05
0.54-0.05,0.54+0.05 =
(0.49,0.59)
In repeated sampling,the true proportion of country residents in favor of offering incentives to high-tech industries to build plants in the country will fall in the interval (0.49,0.59)
Answer:
1 5/36
Step-by-step explanation:
need a common denominator which would be 36
to get from 9 to 36 you multiply by 4 so 5 would be multiplied by 4 to get the fraction 20/36
do the same with 7/12 12x3 is 36 and 7x3 is 21 so 21/36
then add 20+21=41
put over 36 41/36
Find if you can lower it which you can:
41 is bigger than 36 by 5 so your ending fraction would be 1 and 5/36 because 5 and 36 don't have a common factor.
