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

Fail to reject the null hypothesis

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

your answer is b.

x = 33.9

y = 65.6

step-by-step explanation:

might be the correct answer will be question number 2
