Use the t-distribution and the given sample results to complete the test of the given hypotheses. assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal. test vs using the fact that the treatment group (t) has a sample mean of 8.6 with a standard deviation of 4.1 while the control group (c) has a sample mean of 11.2 with a standard deviation of 3.4. both groups have 25 cases.(a) give the test statistic and the p-value.

goog may be able to you find that answer

50-60=10

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
