Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
<h3>What is the discrete probability distribution?</h3>
Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

<h3>How can a person report results of a Mann-Whitney U test?</h3>
In the act of reporting the results of a Mann–Whitney test, it is very vital to state:
- The measure of the central tendencies that pertains to the two groups (means or medians)
- One need to state the value of U.
- One need to state the sample sizes.
- One need to state the significance level.
<h3>What do Mann-Whitney U test results mean?</h3>
The Mann-Whitney U test is known to be one that is often used to make a kind of comparison if or not there exist some difference in the dependent variable for two independent groups.
Note that it often compares if the distribution of the dependent variable is similar for the two groups and as such, The format style of Reporting Mann-Whitney U test results APA is said to be given in the image attached.

May also be conserved, I had this on my test awhile ago and gotten it correct, I forgot why my teacher told me I was right though
