I think it’s 49 cause it’s definitely more than 7 and the other two options seem far too high and unreasonable so it’s most likely 49 :)

Sample size: A researcher is trying to decide how many people to survey. Which of the following sample sizes will result in a co
oksian1 [2.3K]

Answer:

Step-by-step explanation:

Given that a researcher is trying to decide how many people to survey.

We have confidence intervals are intervals with middle value as the mean and on either side margin of error.

Confidence interval = Mean ± Margin of error

Thus confidence interval width depends on margin of error.

Margin of error = Critical value *\frac{\sigma}{\sqrt{n} }

Thus for the same confidence level and std deviation we find margin of error is inversely proportional to square root of sample size.

Hence for small n we get wide intervals.

So if sample size = 300, the researcher will get wider confidence interval

Answer:

Carla lives 16 miles from the Library.

The mistake is drawng the diagram incorrectly and using the miles given in the wrong places. The <u>student's</u> diagram has Yuri in a place that's Southwest of the Library in the diagram given

Step-by-step explanation:

If Yuri lives 24 miles SOUTH of the library, the "b" side of the triangle should be 24, with the Library at the top and Yuri at the bottom left, which is the west end of the base. The base "a" of the triangle should extend 10 to the right (East in compas directions) forming the right angle. Carla lives at the sharp southeast corner of the triangle, and the Hypotenuse "c"  from her house to the Library is the distance we have to figure.

c² =a² + b²

c² = 10² + 24²

c² = 100 + 576

c² = 676

√c² = √676

c = 26       Carla lives 26 miles from the Library.

Answer:

Angle 5, 4, and 7.

Step-by-step explanation:

Angle 2 is vertical to angle 5, making them congruent.


Angle 2 corresponds with angle 4, making them congruent.


Angle 2 is an alternate interior to angle 7, making them congruent.

]

The rest of the angles just combine with angle two to make 180.
