Two samples are selected from the same population. for each of the following, calculate how much difference is expected, on average, between the two sample means. a. one sample has n = 4, the second has n = 6, and the pooled variance is 60. b. one sample has n = 12, the second has n = 15, and the pooled variance is 60. c. in part b, the sample sizes are larger but the pooled variance is unchanged. how does larger sample gravetter, frederick j. statistics for the behavioral sciences (p. 333). cengage learning. kindle edition.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

i^413 x i^0 = 0 as any number multiplied by a zero is

happy to

pls mark as brainliest.

f(x)=4

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.
