Answer:

2\ pints

Step-by-step explanation:

step 1

Find the area of the wall

The area of the rectangular wall is

A=(8)(10)=80\ ft^{2}

step 2

Using proportion find out how many pints Kim needs to paint the wall

so

\frac{1}{42}\frac{pint}{ft^2}=\frac{x}{80}\frac{pints}{ft^2}\\\\x=80/42\\\\x=1.9\ pints

Round to the nearest whole number

1.9=2\ pints

in a random sample of 200 people, 154 said that they watched educational television. fine the 90% confidence interval of the tru
melisa1 [442]

Answer:

[0.7210,0.8189] = [72.10%, 81.89%]

Step-by-step explanation:

The sample size is  

n = 200

the proportion is

p = 154/200 = 0.77

<em>Since both np ≥ 10 and n(1-p) ≥ 10 </em>

<em>We can approximate this discrete binomial distribution with the continuous Normal distribution. As the sample size is large enough, not applying the continuity correction factor makes no significant  difference. </em>

The approximation would be to a Normal curve with this parameters:

<em>Mean </em>

p = 0.77

<em>Standard deviation </em>

\bf s=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.77*0.23}{200}}=0.0298

The 90% confidence interval for the proportion would be then  

\bf  [0.77-z^*0.0298, 0.77+z^*0.0298]

where \bf z^* is the 10% critical value for the Normal N(0,1) distribution , this is a value such that the area under the N(0,1) curve outside the interval \bf [-z^*,z^*] is 10%=0.1

We can either use a table, a calculator or a spreadsheet to get this value.

In Excel or OpenOffice Calc we use the function

<em>NORMSINV(0.95) and we get a value of 1.645 </em>

The 90% confidence interval for the proportion is then

\bf  [0.77-1.645^*0.0298, 0.77+1.645^*0.0298]=[0.7210,0.8189]

This means there is a 90% probability that the proportion of people who watch educational television is between 72.10% and 81.89%

If the television company wanted to publicize the proportion of viewers, do you think it should use the 90% confidence interval?

Yes, I do.

Darya [45]

Answer:

If there's 10 cookies in the jar, and if 2 are peanut butter, the fraction for peanut butter cookies is 1/5, simplified.

Step-by-step explanation:

<u>Given:</u>

  • 10 Cookies Total
  • 3 are Oreo cookies
  • 2 are peanut butter cookies
  • 4 are chocolate chip cookies
  • 1 is a sugar cookie

Bolded text represents what we'll be focusing on.

2 of the cookies are peanut butter, and there's 10 cookies total.

As a fraction, the peanut butter cookies are represented as:

2/10.

2/10 represents 2 peanut butter cookies out of 10 cookies altogether.

<u>Simplify:</u>

2/10 can be simplified by dividing both numerator and denominator by 2:

Quotient: 1/5.

1/5 is your answer.
