I love your profile I watch Jaden Animations too ✨

What the sample suggests is that; the mean body temperature couldvery possibly bevery possibly be 98.6 °F.
<h3>What is the Confidence Interval?</h3>
For a 99% Confidence Interval and DF = 103 - 1 = 102, the value of z = 2.33.
The formula for confidence interval is;
CI = x⁻ ± z(σ/√n))
We are given;
Sample mean; x⁻ = 98.9
standard deviation; σ = 0.67
sample size; n = 103
Thus the confidence Interval is;
CI = [98.9 - 2.33(0.67/√103)], [98.9 + 2.33(0.67/√103)]
CI = (98.9 - 0.154, 98.5 + 0.154)
CI = (98.36, 98.64)
Thus, 98.6 is contained within the 99% CI,and so we can conclude that the the mean body temperature could very possibly bevery possibly be 98.6 °F.

The given question lacks the choices, however, the correct question with choices are:
hydrochloric acid is a strong acid. acetic acid is a weak acid. which statement about hydrochloric acid and acetic acid is correct?
- a. If the initial concentration of each acid is the same, then acetic acid will produce more H, 3, O, +, ions than hydrochloric acid..
- b. A solution of hydrochloric acid at equilibrium will have a greater concentration of solute than a solution of acetic acid at equilibrium.
- c. The pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.
- d. The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
The correct statement about hydrochloric acid and acetic acid is: D. The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
Acid strength is the ability of an acid to dissociate into a proton and an anion. The extent of dissociation of an acid in solution is shown by the dissociation constant.
- A strong acid splits or ionizes to completely or totally dissociates in a water solution
- A weak acid occasionally dissociates in a water solution.
Thus, The correct statement about hydrochloric acid and acetic acid is: D. The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
