In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five tre
yawa3891 [41]

Answer:

MSE = 10

Step-by-step explanation:

Given

SSTR = 200

SST = 800

Required

Determine MSE

This is calculated as:

MSE = \frac{1}{ddf} * SSE

Where:

SSE = SST - SSTR

ddf \to denominator df

So, we have:

SSE = 800 - 200

SSE = 600

To calculate the df, we have:

r = 13 --- observations

n = 5 treatments

So:

ddf = Total\ df - Numerator\ df

Total = n*r-1 = 5*13 -1 = 64

Numerator =n - 1 = 5 - 1 =4

ddf =64-4=60

So, we have:

MSE = \frac{1}{ddf} * SSE

MSE = \frac{1}{60} * 600

MSE = 10

21. Jesse saved his allowance all summer to by a wake board. He put $36.50 in his piggy bank every two weeks for 3 months. He sp
ddd [48]

So lets start out this problem with the initial amount of money jesse has:

$36.50 x (2 (times a month)) x (3 months) = $219

Then, you take 1/4 of his money (which can be converted to the decimal 0.25) and you subtract it from $219

$219 - ($219 x 0.25)

$219 - $54.75 = $164.25

Next, you have to subtract Jesse's lunch ($14.25) from the money he has left after purchasing his tow rope and bathing suit.

$164.25 - $14.25 = $150

Jesse's wake board cost him $150.

DochEvi [55]
28,000 +3,000= 31,000 +3,000 = 34,000 +3,000 = 37,000 +3,000 = 40,000 +3,000 = 43,000 + 3,000 = 46,000

36,000 +2,000= 38,000 +2,000 = 40,000 +2,000 = 42,000 +2,000 = 44,000 +2,000 = 46,000
 
THE SALARY WOULD BE 46,000
 IT WOULD TAKE 6 YEARS

I hope i did that right
