In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations). also, the design provided the following information. sstr = 200 (sum of squares due to treatments) sst = 800 (total sum of squares) the mean square due to error (mse) is a. 600. b. 10. c. 50. d. 200.

 b. 10

Step-by-step explanation:

Given : In a completely randomized experimental design, total treatments : k= 5

Number of observations : n= 65

Sum of Squares Due to Treatments :  SSTR = 200

Total Sum of Squares : SST = 800

Degree of freedom for SSTR (Sum of Squares Due to Treatments) = n-k

= 65-5 = 60

Sum of squares within treatments : SSE =  SST-  SSTR

=800-200= 600

Then, the mean square due to error will be :

Hence, the mean square due to error (MSE) is 10.

Thus , the correct option is b. 10                                                    

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
