Of 560 samples of seafood purchased from various kinds of food stores in different regions of a country and genetically compared
frutty [35]

Answer:

a) (0.5256,0.5944)  

c) Criticism is invalid

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 560

Proportion of mislabeled = 56%

\hat{p} = 0.56

a) 90% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.64

Putting the values, we get:

0.56\pm 1.64(\sqrt{\dfrac{0.56(1-0.56)}{560}}) = 0.56\pm 0.0344\\\\=(0.5256,0.5944)

b) Interpretation of confidence interval:

We are 90% confident that the true proportion of all seafood in the country that is mislabeled or misidentified is between 0.5256 and 0.5944 that is 52.56% and 59.44%.

c) Validity of criticism

Conditions for validity:

np > 10\\n(1-p)>10

Verification:

560\times 0.56 = 313.6>10\\560(1-0.56) = 246.4>10

Both the conditions are satisfied. This, the criticism is invalid.

(3n2 – 5n + 6) + (–8n2 – 3n – 2) =
Troyanec [42]
Hello!

You add like terms

3n^{2} + - 8n^{2} =  -5n^{2}

-5n + -3n = -8n

6 + -2 = 4

Put all the answers together

-5n^{2} -8n+4

The answer is -5n^{2} -8n+4

Hope this helps!

A competitive cliff diver jumps into
fredd [130]

Answer:

2.25 seconds

Step-by-step explanation

d=16t^{2}

d=81 feet\\t=?

Because you know what distance equals you can plug it into the equation

81=16t^{2}

From there you can solve by dividing the 16 over and then square rooting.

\frac{81}{16}=t^{2}

5.0625=t^{2}

You take the square-root to get rid of t^{2}

\sqrt{5.0625} =\sqrt{t}^{2}

t=2.25
