Suppose a population parameter is 0.8, and many large samples are taken

Mathematics
1 answer:
iragen [17]2 years ago
5 0

Using the Empirical Rule, it is found that standard deviation of the sample proportions is of 0.058.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

0.684 and 0.916 is within 2 standard deviations of the mean(below and above), hence there are 4 standard deviations between these measures, so:

4s = (0.916 - 0.684)

s = (0.916 - 0.684)/4

s = 0.058.

The local newspaper has letters to the editor from 10 people. If this number represents ​2% of all of the​ newspaper's readers,
RideAnS [48]

Answer:

The newspaper has 500 readers.

Step-by-step explanation:

We have that:

10 people is 2$ of all newspapers readers, which total t. This means that:

0.02t = 10

t = \frac{10}{0.02}

t = \frac{1000}{2}

t = 500

The newspaper has 500 readers.

Find the area of the parallelogram whose sides are given by vectors a and b. Use the cross product only.
MaRussiya [10]

9514 1404 393

Answer:

  √869 ≈ 29.48 square units

Step-by-step explanation:

The vector cross product is ...

  (3·1 -5·4, -6·1 +2·4, 6·5 -2·3) = (-17, 2, 24)

The area is the magnitude of this vector, so is ...

  √((-17)² +2² +24²) = √(289 +4 +576) = √869 ≈ 29.48

The area is about 29.48 square units.

Which point shows the location of 5 – 2i on the complex plane below? On a coordinate plane, points A, B, C, and D are shown. Poi
Romashka-Z-Leto [24]

Answer:

The Point C shows the location of 5-2i in the complex plane: 5 points to the right of the origin and 2 points down from the origin.

Step-by-step explanation:

We have the complex number 5-2i and we have to show the location of the point that represents that number in the complex plane

In the complex plane the real numbers are located in the horizontal axis, increasing to the right. The positives real numbers are at the right of the origin and the negatives to the left.

The complex numbers are located in the vertical axis, with the positives over the origin and the negatives below the origin.

This complex number 5-2i is the sum of a real part (5) and a imaginary part (-2i), so the point will be 5 units rigth on the horizontal axis (for the real part) and 2 units down in the vertical axis (for the imaginary part).
