SSDF MS Among Treatments 4855.76 693.68 2.61 Error Total 7518.2617 Step s of 8: What is the sum of squares of sample means about the grand mean? Please round your answer to two decimal places. Answer(How to Enter) 2 Points |?Keypad | |?Tables

Answer 1

From the given table we can calculate

	SS	DF	MS	F
Among treatments	4855.76	7	693.68	2.61
Error	2662.5	10	266.25
Total	7518.26	17

Step 5 of 8

$SS_{among\; treatment}=\sum_in_i(\bar x_i-\bar{\bar x})^2$

This means SS_{among treatment} is the sum of squares of sample means about grand means = 4855.76

Step 6 of 8

The variation of individual masurement about their respective means is SS_error= 2662.50

Step 7 of 8

The critical value of F_7,10 at 0.1 level is 2.4140

Step 8 of 8

As F is greater than critical value at 0.1 level

Yes, F is significant.
