Answer: (0.066,0.116)
Step-by-step explanation:
The confidence interval for proportion is given by :-
Given : The proportion of men have red/green color blindness =
The proportion of women have red/green color blindness =
Significance level :
Critical value :
Now, the 99% confidence interval for the difference between the color blindness rates of men and women will be:-
Hence, the 99% confidence interval for the difference between the color blindness rates of men and women= (0.066,0.116)
Answer:
The choice;
I hope I helped you^_^
Option A: z + 1
Option B: 6 + w
Option D:
Solution:
Let us first define the polynomial.
A polynomial can have constants, variables, exponents and fractional coefficients.
A polynomial cannot have negative exponents, fractional exponents and never divided by a variable.
<u>To find which expressions are polynomial:</u>
Option A: z + 1
By the definition, z + 1 is a polynomial.
It is polynomial.
Option B: 6 + w
By the definition, 6 + w is a polynomial.
It is polynomial.
Option C:
Here, y have fractional exponent.
So, it is not a polynomial.
Option D:
By the definition, is a polynomial.
It is polynomial.
Hence z + 1, 6 +w and are polynomials.
