In a sample of 150 cars, 18 cars failed a safety inspection. The sampling method had a margin of error of 0.02.

What is the interval estimate for the proportion that would fail in the form (lower limit, upper limit)?

(0.07,0.11)

(0.10,0.14)

(0.12,0.16)

(0.13,0.17)

(0.10,0.14)

Step-by-step explanation:

-Given the sample size is 150 and our proportion is 18.

-We first determine the proportion's probability:

-The interval estimate for the proportion is then calculated using the formula:

Hence, the interval estimate is for the proportion (0.10,0.14)

the answer is 375 miles

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
