Answer:

The answer is -2, -17

Step-by-step explanation:

You write a system of equations

$x_{1} +x_{2}=-19\\x_{1}-x_{2}=15$

Then you solve:

-2, -17

The confidence interval formula is computed by:

Xbar ± Z s/ sqrt (n)

Where:

Xbar is the mean

Z is the z value

S is the standard deviation

N is the number of samples

So our given are:

90% confidence interval with a z value of 1.645

Sample size 40, 45

Mean 180, 179

Standard deviation 2, 4

So plugging that information in the data will give us a confidence interval:

For 1:

Xbar ± Z s/ sqrt (n)

= 180 ± 1.645 (2 / sqrt (40))

= 180 ± 1.645 (0.316227766)

= 180 ± 0.520194675

= 179.48, 180.52

For 2:

Xbar ± Z s/ sqrt (n)

= 179 ± 1.645 (4 / sqrt (45))

therefore, the answer is letter b

1. When you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is mo

sladkih [1.3K]

Answer:

The eighth of an inch scale measures more precisely.

Step-by-step explanation:

An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{8} =0.125$ inch.

Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{4} =0.25$ inch.

Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)
