A normal population has the mean of 10 and the variance of 25 . A random sample of size n-28 is selected.
(a) Find the standard deviation of the sample mean. Round your answer to two decimal places (e.g. 98.76)
(b) How large must the sample be if you want to halve the standard deviation of the sample mean?

Answers

Answer:

Step-by-step explanation:

Given that:

population mean = 10

variance [tex]\sigma^2[/tex] = 25  ; [tex]\sigma[/tex] =[tex]\sqrt{ 25}[/tex] = 5

sample size n = 28

The standard deviation of the sample mean:

= [tex]{\dfrac{5}{\sqrt{28}}[/tex]

= 0.95

To halve the standard deviation of the sample mean, the size of how large the sample will be can be computed as follows:

[tex]\dfrac{sd_1}{sd_2} = \dfrac{\dfrac{\sigma}{\sqrt{n}} }{\dfrac{\sigma}{\sqrt{n}} }[/tex]

[tex]\implies \dfrac{\dfrac{5}{\sqrt{28}} }{\dfrac{5}{\sqrt{28}} }[/tex]

[tex]= \dfrac{5}{\sqrt{28}} \times \dfrac{\sqrt{28}}{5}[/tex]

= 2

n = 4 × 28

n = 112

The standard deviation is 0.95 and if the standard deviation is halved then the sample mean is 112.

What is a standard deviation?

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

A normal population has a mean of 10 and a variance of 25.

A random sample of sizes n-28 is selected.

A.  The standard deviation will be

[tex]\sigma = \dfrac{\sqrt{Var(x)}}{n} \\\\\sigma = \dfrac{\sqrt{25}}{\sqrt{28}} \\\\\sigma = 0.95[/tex]

B.  The sample be if you want to halve the standard deviation of the sample mean

[tex]\rm \dfrac{SD_1}{SD_2} = 2 = \dfrac{\sqrt{n}}{\sqrt{28}}\\\\n = 4*28 \\\\n= 112[/tex]

A chocolate company makes chocolate malt balls that have a radius of 0.34
inches. The carton they are to be packed in is approximately a rectangular prism with
dimensions 1.5 inches by 2.5 inches by 6 inches. How many malt balls will fit in the
carton

Answers

Answer:

Approximately 141 malt balls

Step-by-step explanation:

this problem is on the mensuration of solids shapes.

first we need to calculate the volume of the rectangular prism

volume of prsim= l*b*h

given that

length= 1.5 in

breath=2.5 in

hieght= 6 in

volume= 1.5*2.5*6

volume=22.5 in^3

secondly we then calculate the volume of a malt ball

given that

raduis r= 0.34

volume of sphere = 4/3πr^3

volume of sphere = 4/3*3.124*(0.34)^3

volume of sphere = 1.33*3.142*0.039

volume of sphere = 0.16 in^3

now we can calculate the amount of sphere that can fit into the prism as

= volume of prism/volume of sphere

= 22.5/0.16

=140.6

approximately 141 malt balls

Complete Question

The complete question is shown on the first uploaded image

Answer:

The  value is  [tex]v(3) =  29.4 \  m/s[/tex]

Step-by-step explanation:

From the question we are told that

    [tex]s(t) =  -4.9t^2 + 500[/tex]

And  

    [tex]\lim_{t \to a}  \frac{s(a) - s(t)}{a-t}[/tex]

Generally s(t) at t = a is mathematically evaluated as

      [tex]s(a) =  -4.9a^2+ 500[/tex]

So

    [tex]s(a) - s(t) =  -4.9a^2 + 500 - ( -4.9t^2+500)[/tex]

     [tex]s(a) - s(t) =  -4.9a^2 + 500 +4.9t^2-500)[/tex]

      [tex]s(a) - s(t) = 4.9(t^2 - a^2)[/tex]

Thus the velocity is represented as

     [tex]v(t) =\lim_{t \to a}  \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 -  a^2 )}{ a-t}[/tex]

=>     [tex]v(t) = \lim_{t \to a}  - 4.9(a + t )[/tex]

=>      [tex]v(t) = -4.9 (a + a )[/tex]

=>      [tex]v(t) = -9.8a[/tex]

Now at  t =  3

=>  [tex]v(3) = -9.8 (3)[/tex]

=>   [tex]v(3) =  29.4 \  m/s[/tex]


2. A stock price rose 2.2 points in
Week 1. The stock price fell 5.4
points in Week 2. Write and solve
an equation to represent the total
price change in stock.

Answers

Answer: the total  price change in stock is fall of 3.2 points or -3.2 points.

Step-by-step explanation:

In integers , we use positive integers to show rise in amount whereas we use negative integers to show fall .

Given: A stock price rose 2.2 points in  Week 1.

i.e. +2.2 points rise.

The stock price fell 5.4  points in Week 2.

i.e. fall of -5.4.   (Much greater, than it rose)

The equation to represent the total  price change in stock would be

Total  price change = price rose in  Week 1 +  price fell  in Week 2.

= [+2.2 + (-5.4)] points

= 2.2 - 5.4 points   [ (+)(-) = (-)]

= -3.2 points

Hence, the total  price change in stock is fall of 3.2 points.

Step-by-step explanation:

The given expression is [tex]\frac{w^{-7}(w^{-9})^2}{w^4}[/tex].

Since, [tex]w^{-7}=\frac{1}{w^7}[/tex]

And [tex]w^{9}=\frac{1}{w^9}[/tex]

Expression will become,

[tex]\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}[/tex]

               [tex]=\frac{1}{w^{25}}\times \frac{1}{w^4}[/tex]

               [tex]=\frac{1}{w^{25}\times w^4}[/tex]
