1). Add bags of gas | balloon goes UP | 3 bags of gas ( +3 ), 10 bags of sand ( +10 )

2). Add bags of sand | balloon goes DOWN | 3 bags of sand ( -3 ), 10 bags of sand ( -10 )

3). Subtract bags of gas | balloon goes <u>DOWN</u> | subtract 3 bags of gas <u> </u><u>-</u><u> </u>(<u> </u><u>+</u><u>3</u><u> </u>), subtract 10 bags of gas <u> </u><u>-</u><u> </u>(<u> </u><u>+</u><u>1</u><u>0</u><u> </u>)

4). Subtract bags of sand | balloon goes <u> </u><u>U</u><u>P</u><u> </u> | subtract 3 bags of sand <u> </u><u>-</u><u> </u>(<u> </u><u>-</u><u>3</u><u> </u>), subtract 10 bags of sand <u> </u><u>-</u><u> </u>(<u> </u><u>1</u><u>0</u><u> </u>)

Answer:

A. Independent samples

Step-by-step explanation:

This experiment is comparing the results between two independent samples. Paired samples consist of data for which each point in one sample would be paired to a specific data point in another sample.

The standard IQ test is designed so that the mean is 100100 and the standard deviation is 1515 for the population of all adults.
Natalija [7]

Answer:

The sample size should be approximately 151.      

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 100

Population standard deviation, σ = 15

We have to evaluate the sample size, n.

Alpha, α = 0.10

Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

100 \pm 1.64(\frac{15}{\sqrt{n}} ) = (98,102)

100 \pm 1.64(\displaystyle\frac{15}{\sqrt{n}} ) = (98,102)\\\\1.64(\frac{15}{\sqrt{n}} ) = 2\\\\n = 151.29 \approx 151

Thus, the sample size should be approximately 151.
