Answer:

3 treatment conditions were compared in the study.

14 individuals participated in the study.

Step-by-step explanation:

Consider the provided information.

Part (A) How many treatment conditions were compared in the study?

There are two sets of degrees of freedom; one for the numerator and one for the denominator.

F ratio is defined as: $df=(df_{\text{Between treatment}}, df_{error})$

The formula for between treatment is: $df_{\text{Between treatment}}=k-1$

Substitute $df_{\text{Between treatment}}=2$ in above formula.

$2=k-1$

$k=3$

Therefore, 3 treatment conditions were compared in the study.

Part (B) How many individuals participated in the study?

The error degree of freedom is $df_{error}=(k-1)(n-1)$

Substitute $df_{error}=26$ and k=3 in above formula.

$26=(3-1)(n-1)$

$26=2(n-1)$

$14=n$

Hence, 14 individuals participated in the study.

90% of a number is x . What is 100% of the number? Assume x>0

mariarad [96]

Step-by-step explanation:

Let the required number be n

$\therefore \: \frac{90}{100} \times n = x \\ \\ \therefore \: \frac{9}{10} \\ \\ \therefore \:n = \frac{10}{9} x \\ \\ \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\ \\ = \frac{10}{9} x \times \frac{100}{100} \\ \\ = \frac{10}{9} x \\$

NOTE: A number is always 100% in itself.
