There were 2430 Major League Baseball (MLB) games played in 2009, and the home team won in 54.9% of the games. If we consider th

Answer:

Confidence interval @ 90% = [0.5324 < p < 0.5656]

Step-by-step explanation:

We are given the following information:

Sample size (n) = 2430

Proportion of win (p) = 0.549

Proportion of loss (q) => 1-p = 0.451

By formula of confidence interval,

CI = p ± Z(90%) * $\sqrt{\frac{p*(1-p)}{n}}$ ,

CI = 0.549±(1.645* ((0.549*(0.451))/2430))^(0.5)

CI = [0.5324 < p < 0.5656]

Let P(x,y) be a propositional function if ꓯyꓱxP(x,y) is true does it necessarily follow that ꓱxꓯyP(x,y) is true? Justify your an

andrew11 [14]

Answer:

It is NOT TRUE

Step-by-step explanation:

ꓯyꓱxP(x,y)

means that for each value of y there exist x such that P(x,y) is true

whereas

ꓱxꓯyP(x,y)

means that there exists x such that for each value y, P(x,y) is true.

In the second case, the same x must work for every element y.

Counter-example

Consider

P(x,y) the following proposition

x-y = 0, for x, y integers.

Given an integer y, there is another integer x (namely, x=-y) such that

x-y = 0

so, ꓯyꓱxP(x,y) is TRUE

If ꓱxꓯyP(x,y) were TRUE, then would exist a single unique value of x such that P(x,y) is TRUE for every integer y.

Then P(x,1) and P(x,2) would be both TRUE and

x-1 = 0

x-2 = 0

and we conclude 1=2, which is a contradiction.

So ꓱxꓯyP(x,y) is NOT TRUE (FALSE)
