A random sample of 40 people was asked if they had watched the current episode of a hit television series. The following data represent their responses. yes no no ono no no no yes no no
no no es no no no no no no no no
yes no yes no noyes no no no no
no no no no no no no

Required:
a. Calculate the proportion of viewers in the sample who indicated they watched the current episode.
b. Compute a 99% confidence interval for the proportion of viewers who watched the current episode (Round to three decimal places as needed.)

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
