andrew11 [14]

Divide 8 by 6 and you will get 1 and 1/3 pounds per dog. You can draw 6 dogs, then equally assign the pounds of dog food to each dog. I would not recommend this technique, however.

Mamont248 [21]

Answer:

8 nickels

Step-by-step explanation:

Let n be the number of nickels.

4: (2+ 6 + 4 + n) = 1:5

4÷(12 + n) = 1÷5

4 x 5 = 1 x (12 + n)

20 = 12 + n

n = 8

N1=731pˆ1=0. 33 n2=644pˆ2=0. 28 use this data to find the 90onfidence interval for the true difference between the population pr

postnew [5]

The 90% confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]

Given,

$N_{1}$ = 731

$N_{2}$ = 644

$P_{1}$ = 0.33

$P_{2}$ = 0.28

z score for 90% confidence interval = 1.645

Here, the confidence interval formula :

( $P_{1} -P_{2}$ ) ± z $\sqrt{\frac{P_{1}(1-P_{1}) }{N_{1} }+ \frac{P_{2}(1-P_{2}) }{N_{2} } }$

Substituting the values, we get

(0.33 - 0.28) ± 1.645 $\sqrt{\frac{0.33(1-0.33)}{731}+\frac{0.28(1-0.28)}{644} }$

= 0.05 ± 1.645 $\sqrt{0.0003024624+0.0003130435}$

= 0.05 ± 1.645 $\sqrt{0.0006155059}$

= 0.05 ± 1.645 × 0.0248093914

= 0. 05 ± 0.0408114489

Confidence interval:

- 0.05 - 0.0408114489 = - 0.0908114489 ≈ - 0.0908

- 0.05 + 0.0408114489 = - 0.0091885511 ≈ - 0.0092

The confidence interval for the true difference between the population proportions is [ - 0.0908, - 0.0092]
