Considering the p-value of 0.6, the decision is that we do not reject the null hypothesis.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, we test if the proportions are equal, that is:

H_0: p_g = p_k


At the alternative hypothesis, we test if they are different, that is:

H_1: p_g \neq p_k

<h3>What is the decision rule?</h3>
  • If the p-value is greater than the significance level, we do not reject the null hypothesis.
  • If the p-value is less than the significance level, we reject the null hypothesis.

In this problem, the significance level is of 0.1, while the p-value is of 0.6, hence the correct decision for the test is to not reject the null hypothesis.

ibuprofen, c13h18o2, is a common medicine for treating mild pain, fever, and inflammation. a concentrated stock solution of 0.02
pickupchik [31]

Answer:

26.2ml

Explanation:

This is a delusion calculation. But before performing the delusion we need to know the concentration the polarity of the original solution. The original solution was prepared by taking .021 mg of ibuprofen and dissolving it in one mil leader. So to calculate the concentration, we need to take the moles of ibuprofen, which can be calculated by taking the milligrams divided by 1000 to get grams and then divided by the molar mass to get moles and dividing the moles of ibuprofen by the leaders of the solution. One mil leader can be calculated, Can be converted into a leader by dividing by 1000. We then get a polarity of 1.018 times 10 to the negative for Mueller Than to carry out the dilution. We have a 1.018 times 10 to the negative for Mueller solution and one mil leader of it. We want to prepare 375 times 10 to the negative six molar solution. And so we need to figure out what the new total volume will be Rearranging. This equation gives us a total volume of 27.15 million l but we already have one mil leader of solution. So we need to add to that The 27.15 -1 or the 26.15 ml. The answer then of the choices available would be 26.2 ml
