frez [133]

Step-by-step explanation:

Dosage per kg per day = 8mg

2 doses = 4mg

If a person weighs 82 pounds =? mg

1kg = 2.205 pounds

So 82 ÷ 2.205 = 37. 195 kg

So he should receive 37. 195 mg every 12 hours

Using confidence interval concepts, it is found that the incorrect statement is given by:

B. The population proportion is 0.80.

In a sample of n people with a proportion of $\pi$ , and a confidence level of $1-\alpha$ , we the confidence interval for the proportion is:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

80 developed immunity out of 100, thus, the sample proportion is:

$\pi = \frac{80}{100} = 0.8$

Option A is correct.

The standard error is:

$s = \sqrt{\frac{\pi(1-\pi)}{n}}$

Considering $n = 100$

$s = \sqrt{\frac{0.8(0.2)}{100}} = 0.04$

Thus, statement E is correct.

90% confidence level, thus the critical value is the value of z that has a p-value of $1 - \frac{0.05}{2} = 0.975$ , so $z = 1.645$ , which means that statement D is correct.

The margin of error is:

$M = zs = 1.645(0.04) = 0.0658$

Thus, statement C is correct, which leaves B as the false statement, as we have the sample proportion, and we can only estimate, not guarantee the population proportion.

nonlinear optimization problem is any optimization problem in which at least one term in the objective function or a constraint

Varvara68 [4.7K]

True, the nonlinear optimization problem is an optimization problem in which at least one term in the objective function or a constraint is nonlinear.

Given that,
A statement of nonlinear optimization is given,
We have to determine whether the statement is true or false.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,

The nonlinear optimization problem is an optimization problem in which at least one term in the objective function or a constraint is nonlinear, is true, Because its basic definition of nonlinear optimization.

Thus, the given statement is true.
