A study done a a polling organization Randomly surveyed 1031 adults by phone. The poll found that 42%of the respondents said they spend less than three hours a day watching TV. Based on this finding calculate to 2 decimals places the ((%confidence interval for the proportion of US adults who spend less than three hours watching TV on an average day. a) [.35, .45]
b) [.38, .46]
c) [.41, .43]
d) [.30, .50]
e) [.32, .52]

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

answer:
