Determine the better of the two alternatives using the present worth analysis. Use an interest rate of 10%.

Alt. X Alt. Y

Initial cost $12,500 $8,900

Annual benefit $6,800 $2,000

Salvage value $5,000 $8,900

Life in years 2 years 3 Years

MARR 10%

Alternative X gives a better net present worth of $3433.88 compared to Alternative Y with a present networth of $ 2,760.41  

Step-by-step explanation:

Using the present analysis which is also the net present value analysis,the net present of the two alternatives can be compared so as to  choose the project with the higher net present worth.

The net present is simply discounting the project cash flows in order to know their worth today as calculated below

Alternative X present net-worth

=-$12500+($6800*1/(1+10%)^1)+($6800+$5000)*1/(1+10%)^2=$ 3,433.88  

Alternative Y present net-worth

=-$8900+($2000*1/(1+10%)^1)+($2000*1/(1+10%)^2)+($2000+$8900)*(1/(1+10%)^3)=$2,760.41  

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
