Answer:

B.

Explanation:

Based on the sampling methods provided in regards to the question it can be said that the method being used is called Simple Random. This refers to dividing the population into different group which are then chosen at random, giving each group an equal chance of getting chosen. Which is exactly what is going on in this scenario, as the day is divided into three parts and her mood is measured randomly during each part of the day.

Lesechka [4]

Answer:

See explaination for the code

Explanation:

def wordsOfFrequency(words, freq):

d = {}

res = []

for i in range(len(words)):

if(words[i].lower() in d):

d[words[i].lower()] = d[words[i].lower()] + 1

else:

d[words[i].lower()] = 1

for word in words:

if d[word.lower()]==freq:

res.append(word)

return res

Note:

First a dictionary is created to keep the count of the lowercase form of each word.

Then, using another for loop, each word count is matched with the freq, if it matches, the word is appended to the result list res.

Finally the res list is appended.
