An environmentalist wants to find out the fraction of oil tankers that have spills each month. Suppose a sample of 313 tankers is drawn. Of these ships, 235 did not have spills. Using the data, construct the 80 % confidence interval for the population proportion of oil tankers that have spills each month. Round your answers to three decimal places.

answer: 2/4

step-by-step explanation:

146%

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
