Answer: 0.05
Step-by-step explanation:
- Sampling error is the error occurs by considering sample for study instead of entire population.
Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.
Sample size : n= 100
Sample proportion of items in a population that possess a specific attribute :
Now, the formula to find the sampling error :
Hence, the sampling error =0.05
The figure can be splitted into 2 trapeziums.
Hence, 14.5 * 16 + 20 * 10 = 432.
X^2+12x<-11
add 11 both sides
x^2+12x+11<0
wht 2 numbres multiply to get 11 and add to get 12
11 and 1
(x+1)(x+11)<0
at x=-1 and x=-11
test other numbers
x=-10 gives us -9<0, true
x=-12 gives us 13<0, false
x=0 give us 0<0, false
so it is the range of numbers from -1 to -11
-11<x<-1
