The option that is the best course of action when a case has the majority of data missing is option D. Delete the case.
What is the data about?Deleting cases with missing data, also known as listwise deletion, is a common method for dealing with missing data in statistical analyses. This method removes any cases that have missing data for any of the variables, which is appropriate when the majority of data is missing.
The other options, such as ignoring the fact that there are missing data, computing summed scores, or deleting variables, would likely lead to biased or inaccurate results.
So, It is important to note that deleting cases with missing data will reduce the sample size and potentially lead to loss of power and inferential errors. .

write a program to determine whether a number n is equal to the sum of its proper positive divisors excluding the number itself
Here is a program in Python that determines whether a number n is equal to the sum of its proper positive divisors (excluding the number itself):
def is_perfect(n):
divisors = []
for i in range(1, n):
if n % i == 0:
divisors.append(i)
if sum(divisors) == n:
return True
else:
return False
n = int(input("Enter a number: "))
if is_perfect(n):
print(n, "is a perfect number.")
else:
print(n, "is not a perfect number.")
The function is_perfect(n) takes an integer n as input, and uses a for loop to find all the positive divisors of n, excluding n itself. It then checks if the sum of these divisors is equal to n. If it is, the function returns True, indicating that n is a perfect number. If the sum of the divisors is not equal to n, the function returns False, indicating that n is not a perfect number.
The program prompts the user to enter a number, then calls the is_perfect(n) function to check if the number is a perfect number. If it is, the program prints that the number is a perfect number, otherwise it prints that the number is not a perfect number.
It's important to note that there are not many perfect numbers, and for larger numbers this algorithm could become inefficient. In case you need to work with large numbers, it is more efficient to use the Sieve of Eratosthenes algorithm to generate the perfect numbers.

A company noticed a recent spike in online posting about one of their products. In response, they increased the amount of paid advertising for that particular product. However, sales of the product dropped by 65% in the next 4 months. Which big data value component was missing from the analysis about the spike?
Answer:
missing big data value component from the analysis about the spike could be causality
Explanation:
It appears that the missing big data value component from the analysis about the spike could be causality.
The company noticed a spike in online posting about the product, and in response, they increased the amount of paid advertising for that particular product.
However, this increased advertising did not lead to an increase in sales, but instead, sales dropped by 65%.
This suggests that there may be other factors at play beyond just the spike in online posting that the company was not aware of, and that may have contributed to the decrease in sales.
In order to fully understand the situation, the company should conduct further analysis to understand the cause of the spike in online posting and whether or not there is a causal relationship between that spike and the decrease in sales.

John Dalton presented the atomic theory, which had numerous key components. According to the idea that everything in the universe is made up of small, unbreakable atoms. It also included the mass because only atoms of the same element can share attributes and atoms of other elements have different masses. The law of conservation of mass and the laws of definite and multiple proportions were born out of it. One of the principles states that matter is composed of extremely small units known as atoms.
