recent random survey of 1,000 Americans asked them what they would do with an unexpected tax return. 470 of them indicated they would use it to pay down debt. Calculate a 90% confidence interval for the proportion of all people who would use an unexpected tax refund to pay debt. 1. Calculate p-tilde, the initial estimate for the proportion of people who would pay down debt. Use five decimals for accuracy. 470/1000=0.47000 (471)/(1002)=0.47006 (472)/(1004)=0.47012

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
