A random sample of n 5 4 individuals is selected from a population with m 5 35, and a treatment is administered to each individual in the sample. After treatment, the sample mean is found to be M 5 40.1 with SS 5 48. a. How much difference is there between the mean for the treated sample and the mean for the original population

5.1

Step-by-step explanation:

Given that:

sample size n = 4

the mean of the original population  μ is = 35

and the mean for the sample after treatment M is = 40.1

standard deviation of the sample SS = 48

The difference between the mean for the treated sample and the mean for the original population is therefore calculated as: M -  μ

= 40.1 - 35

= 5.1

The standard error of M is =

The standard error of M is =

The standard error of M is =

The standard error of M is =

The standard error of M is = 24

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
