# An ANOVA procedure is used for data obtained from four populations. Four samples, each comprised of 30 observations, were taken from the four populations. The numerator and denominator (respectively) degrees of freedom for the critical value of F are _____.

Step-by-step explanation:

Given that an ANOVA procedure is used for data obtained from four populations. Four samples, each comprised of 30 observations, were taken from the four populations.

Hence total observations are 30*4 =120

No of groups = 3

Hence numerator df = 3-1 =2

Now total degrees of freedom = 120-1 =119

So denominator degrees of freedom = 119-2 = 117

Thus F statistic will have numerator as 2 degrees of freedom and denominator as 117 degrees of freedom.

Step-by-step explanation:

An urn contains 11 balls, 3 white, 3 red, and 5 blue balls. Take out two balls at random, without replacement. You win $1 for each red ball you select and lose a$1 for each white ball you select. Let X be the random variable that notes the amount you win. Find the probability mass function (p.m.f.) of X.

Given: An urn contains 11 balls, 3 white, 3 red, and 5 blue balls.

You win $1 for each red ball you select and lose a$1 for each white ball you select.

Let X be the number of times you win.

The total number of ways to select 2 balls (order does not matter) =

The number of ways so that two balls are white (and

The number of ways so that two balls are red (and

The number of ways so that one ball is red, one is white (and

The number of ways so that two balls are blue (and ):

i.e.

The number of ways so that one ball is blue, one is white (and ):

The number of ways so that one ball is blue, one is red (and ):

Thus, the probability mass function (p.m.f.) of X would be ( in attachment) :

The correct option is (A) Yes they are similar.

Explanation:
One quadrilateral (the red one) is the scaled version of the other quadrilateral (the blue one).

All you need is to reflect and dilate the blue one to make the red one.

Hence they are similar to each other. The question is asking about similarity; therefore the correct option is (A) Yes they are similar.
