Answer:
Correct option C
Trimmed mean
Explanation:
A trimmed mean is a method of averaging that removes a small designated percentage of the largest and smallest values before calculating the mean.
Trimmed mean helps eliminate the influence of data points on the tails that may unfairly affect the traditional mean.
Trimmed means are used in reporting economic data in order to smooth the results and paint a more realistic picture.
Answer:
An array with such a large size should be sorted using Mergesort algorithm
Explanation:
Mergesort has worst case complexity of O(nlogn) whereas quicksort algorithm has worstcase complexity of O(
). So quicksort works better with smaller arrays and mergesort works better than quicksort in case of larger arrays. Insertion sort is used when array is almost sorted.So, if array is unsorted at greater level, insertion sort should not be used.It also has a worst case complexity of O().
