The paint used to make lines on roads must reflect enough light to be clearly visible at night. let µ denote the true average reflectometer reading for a new type of paint under consideration. a test of h0: µ = 20 versus ha: µ > 20 will be based on a random sample of size n from a normal population distribution. what conclusion is appropriate in each of the following situations? (round your p-values to three decimal ) n = 16, t = 3.3, a = 0.05p-value =(b) n = 8, t = 1.8, a = 0.01p-value =(c) n = 26,t = -0.6p-value =

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.
