Saying "a number" is the same as saying "x"
"Three more than a number" is the same as "three more than x"
If you have three more of something (say, marbles) than someone else, then you have their number of marbles plus three more.
Then, "Three more than x" is the same as "three plus x", or "3 + x"
Hope this helps! :)

Answer from Gauthmath
Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.
<h3>When should the t-distribution and the z-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, σ is not known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.
Using a t-distribution calculator, considering a <em>confidence level of 99%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.
