Test the claim that the proportion of people who own cats is larger than 70% at the 0.10 significance level.

The null and alternative hypothesis would be:

H0:μ=0.7H0:μ=0.7
H1:μ≠0.7H1:μ≠0.7

H0:p≥0.7H0:p≥0.7
H1:p<0.7H1:p<0.7

H0:μ≥0.7H0:μ≥0.7
H1:μ<0.7H1:μ<0.7

H0:μ≤0.7H0:μ≤0.7
H1:μ>0.7H1:μ>0.7

H0:p≤0.7H0:p≤0.7
H1:p>0.7H1:p>0.7

H0:p=0.7H0:p=0.7
H1:p≠0.7H1:p≠0.7

The test is:

left-tailed

right-tailed

two-tailed

Based on a sample of 400 people, 75% owned cats

The test statistic is: (to 2 decimals)

The p-value is: (to 2 decimals)

Based on this we:

Reject the null hypothesis

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
