Answer:

D. n1 and n2 can be of different sizes

Step-by-step explanation:

When we are trying to develop interval estimate for difference between two populations, we first select two samples from these populations. We get the interval using the required statistic.

These are:

- Sample size of both populations. Which are n1 and n2 respectively.

- then the Sample mean of two populations

- sample standard deviation.

The samples of different sample sizes can be used and we are not obligated to make use of the same sample size.

What is the value of X?<br> Help please!
anastassius [24]

Answer:

(11√3)/3

Step-by-step explanation:

In order to solve for the variable, you will need to use a trig function. In this case, you will need to use the trig function tangent.

Tan = opposite/adjacent

⇒ Tan 30° = x/11

⇒ 11 · Tan 30° = x

⇒ (11√3)/3 = x

18.<br> Place parentheses in the following equation to<br> make it true.<br> 4 + 53-8 = 19
soldier1979 [14.2K]

Answer:

(4+5)3-8 = 19

Step-by-step explanation:

1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.

2) Try solving the problems (use PEMDAS)

(4+5)3-8 = 9*3-8 = 27-8 = 19

4+5(3-8) = 4+5(-5) = 4-25 = -21
