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

Which of these triangle pairs can be mapped to each other using a translation and a rotation about point A?
Vladimir79 [104]

Answer:

<u>Figure A</u>

Step-by-step explanation:

See the attached figure which represents the given options

We are to select the correct pair of triangles that can be mapped to each other using a translation and a rotation about point A.

As shown: point A will map to point L, point R will map to point P and point Q will map to point K.

we will check the options:

<u>Figure A</u>: the triangle ARQ and LPK can be mapped to each other using a translation and a rotation about point A.

<u>Figure B: </u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line RA.

<u>Figure C:</u> the triangle ARQ and LPK can be mapped to each other using a translation and a reflection about the line QA.

<u>Figure D:</u> the triangle ARQ and LPK can be mapped to each other using a rotation about point A.

So, the answer is figure A

<u>The triangle pairs of figure A can be mapped to each other using a translation and a rotation about point A.</u>

A veterinarian collects data on the number of times race horses are raced during their careers. The veterinarian finds that the
SpyIntel [72]

Answer:

c. (12.12, 18.48)

Step-by-step explanation:

Hello!

The study variable is X: number of times a racehorse is raced during its career.

The average number is X[bar]= 15.3 and the standard deviation is S= 6.8 obtained from a sample of n=20 horses.

To estimate the population mean you need that the variable has a normal distribution, in this case, we have no information about its distribution so I'll assume that it has a normal distribution. With n=20 the most accurate statistic to use for the estimation is a Students-t for one sample, the formula for the interval is:

X[bar] ± t_{n-1;1-\alpha /2} * \frac{S}{\sqrt{20} }

t_{n-1;1-\alpha /2} = t_{19;0.975}= 2.093

[15.3 ± 2.093 * \frac{6.8}{\sqrt{20} }]

[12.12; 18.48]

Using a significance level of 95% you'd expect that the true average of times racehorses are raced during their career is included in the interval [12.12; 18.48].

I hope it helps!
