A large school district is considering implementing a program that, if successful, would improve the reading scores of its students by 10 points. The current reading scores for the district are normally distributed with a mean of 25 and a standard deviation of 8. The administrators decide to test the new program in one school of 200 students. What is the standard deviation of the comparison distribution

Answers

Answer:

The standard deviation of the comparison distribution is 0.5657.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this question:

Standard deviation of the population is 8, sample of 200. So

[tex]s = \frac{8}{\sqrt{200}} = 0.5657[/tex]

The standard deviation of the comparison distribution is 0.5657.

Answer:

x = - 4

Step-by-step explanation:

Since we are looking at a circle, we know that the sum of all arc angles should add up to 360°. This means that the following...

- 32x - 3 = 360 - 85 - 35 - 115

- 32x - 3 = 125

- 32x = 125 + 3

- 32x = 128

x = 128 / (-32)

x = - 4

The measure of the arc is 214 degrees

What is Circle?

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The measure of the arc FE is 146 degrees.

Measure ED is 90 degrees.

To find the measure of the arc EDF we have to find the measure of DF.

146+90+x=360

236+x=360

Subtract 236 from both sides

x=360-236

x=124

Now let us find the arc measure EDF =Measure of ED + Measure of DF

=90+124

=214 degrees

Hence, the measure of the arc is 214 degrees

find the surface area of a cylinder with the height of 10 inches and a base diameter of 6 in ​

Answers

Answer:

339.24

Step-by-step explanation:

To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2

The radius is half the diameter do r=3

3.14(3)^2 should give you about 28.27.

This is the area of the top and bottom of the cylinder.

Now, do 28.27x10=282.7 to find the height surface area.

282.7+28.27+28.27=Surface area.

Answers

Answer: Rs. 11,520

Step-by-step explanation:

As the method of compounding is not stated, the default of simple interest will be used.

Simple interest is a fixed amount that is paid over the course of the loan and is based on the original amount borrowed.

Formula is:

Amount owed = Amount borrowed * ( 1 + rate * time)

= 8,000 * ( 1 + 8% * 5.5 years)

= 8,000 * 1.44

= rs 11,520

What is the value of x in the figure below?

Answers

Answer:

x = 25°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

The given triangle is a right triangle which means one of its angle has a measure of 90°

since thd other angle is given as 65 to calculate x we just add the given measures and subtract it from 180

90° + 65 + x = 180

155 + x = 180 subtract 155 from both sides

x = 25°
