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:

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

<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.

The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.
<h3>What is pH?</h3>
The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.
The first step to determine the pH of the HF solution is to set up the ICE table as shown;
HF + H2O ⇄ H3O^+ + F^-
I
C
E
The values of the initial concentration of HF as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;
Ka = [H3O^+] [ F^-]/[HF] Knowing that [H3O^+] = [ F^-] = x

Answer:
angle F would be 64 degrees
Explanation:
cause 74 +77+70+39+36= 296 then do 360-296 and you'll get 64 just remember it always has to equal 360 degrees
