Answer 1

Answer

We have to F critical value

we need degree of freedom numerator and denominator

df(numerator) = number groups -1

= 3-1............because we have three groups(asia, europe and north america)

=2

and

df(denominator) = total data values - number of groups

= (7+8+5) - 3

= 20-3

= 17

significance level = 0.10 (given)

Open F critical table and find values for alpha = 0.10

check df1 = 2 in the first row or top most row and check df2 = 17 in the left most column or first column

then select the intersecting cell

we get

F critical = 2.645 (3 decimals)
