Answer:
i think it would be 20%
Step-by-step explanation:
You have to add 9 on both sides and then you have to rewrite the equation with a positive and a negative and then you have to subtract 3 on both sides of each equation then you have to solve each equation to find the answer
The method we need to use here is very particular to this type of a situation. The way we will find that polynomial, or the divisor, is to follow this formula:
. For us that will look like this:
. First we will simplify as much as possible that very long numerator there. It simplifies to
. What you do now is use long division of polynomials, which, unfortunately, is impossible to show in this forum. However, get familiar with the long division process if you are not already, and you will find that your polynomial g(x) is
.
Answer:
Given the information in the question;
a) The parameter of interest is the population of artists who are left-handed and its is 10% = (10/1000 = 0.10
b) The Null hypothesis and alternative hypothesis are;
<em>H₀ : p </em>= 0.10
<em>H₁ : p</em> > 0.10
c) The sample proportion is calculated as:
p = number of left handed artist / sample size
p = 26 / 200
p = 0.13
d) To find the p-value, The researcher should calculate the probability that the sample proportion would be 0.13 or larger for a sample of size 200 if the population proportion is actually 0.10.
