6= 12.7

7= 14.5

8= 16.3

9= 18.1

10= 19.1

11= 21.7

A researcher believes that 12% of a simple random sample of adults will be able to identify a Toyota Scion by brand and model na
DochEvi [55]

Answer: 650

Step-by-step explanation:

When prior estimate of population proportion is known , then the formula to find the required sample size is given by :-

n=p(1-p)(\dfrac{z^*}{E})^2

, where p= population proportion

E= margin of error

z* = Critical value.

Let p be the proportion of adults able to identify a Toyota Scion by brand and model name.

As per given , we have

p = 12%= 0.12

E= 2.5%=0.025

Critical value for 95% confidence interval : z* = 1.960  [By z-table ]

Then, the required sample size = n=(0.12)(1-(0.12))(\dfrac{1.96}{0.025})^2

n=(0.1056)(78.4)^2

n=(0.1056)(6146.56)

n=649.076736\approx650

Thus , the required sample size = 650

Answer:

120 cubes

Step-by-step explanation:

Find the volume of the prism and then divide it by the volume of one cube (which is 1/27 cm):

V = length*width*height = (5/3 cm)(4/3 cm)(2 cm) = 40/9 cm³.

Dividing this result by 1/27 yields

40       27         40*3    

------ * ------ = -------------- = 120

  9        1               1
