Question
Fall 2017 is the probability of the females eating first less than 3 times in a trial day? (3 points) Use the following information and table for questions 2-7 Sargassum mut negatively affects one native species, Macrocystis is an invasive algal species found along the Pacific coast. S. muticum native species, Egregia menziesi, while they have no effect on another is porifera. A research group decides to investigate the spread of S. A muticum in Northern California. Once a month for 5 months, algae within 1x1 meter plots are surveyed and the number of stipes of algae is recorded. The table below is the data recorded for plots A-H for each of the five weeks. Plot A Plot B Plot Plot D Plot E Plot F Plot H 15 12 10 13 Plot G 16 10 14 15 10 13 12 13 14 10 16 13 12 10 14 2. Using the table provided, write out and solve summation notation for each of the following. (3 points each) a. The sum of the natural log of each variate. b. The sum of columns 6-8, rows 1-3. c. The cubed sum of rows land 2.Explanation / Answer
a) sum of the natural log of each variate.
Using Excel function we can find natural log of the given number .
Select any empty cell and plug function as =LN( x)
For first number of the given data =LN(7) = 1.94591
Similarly find log for each number and sum sum of each column is in below table .
b) Sum of column 6-8 and and row 1-3
First we have to find sum of each row and each column as below :
Sum of column 6-8 = 52 + 60 + 64 = 176
Sum of rows 1-3 = 92 + 73 + 81 = 246
c ) Cubed sum of row 1 and 2 :
for finding cub of a number in Excel we have to use equation as : =x^3
For first number of given table =7^3 = 343
Similarly we can find cube of each number and then take sum of each row as follows :
Cubed sum of row 1 and 2 = 16058 + 7849 = 23907
