Answer:
Yes
Step-by-step explanation:
-10 is less than 20
The sum is
<em><u>Solution:</u></em>
Given that we have to find the sum
<em><u>Given expression is:</u></em>
We have to add both the expressions
Addition of two polynomials involves combining like terms present in the two polynomials
Like terms are the terms having same variable and same exponent
From given expression,
Remove the parenthesis and add
Combine the like terms
Add the like terms
Thus the sum is
Answer:
The p-value is 0.025
Step-by-step explanation:
Given that:
30% of the people in Washington state want cell phone use banned in cafes
sample size N = 1450
X = 474 people have the same opinion.
The objective is to calculate the p-value.
Let's assume the level of significance = 5% = 0.05
From the information given ; the null and alternative hypothesis can be computed as:
USING MINITAB; the simulation on what we compute on our MINITAB can be written as:
Test for p = 0.3 vs p not = 0.3
Sample X N Sample p 95 C.I Z-value P-value
1 474 1450 0.326897 (0.302752, 0.351041) 2.23 0.025
From what we have in our MINITAB Output;
Z - value = 2.23
P-Value = 0.025
