Consider the following game, called matching pennies, which you are playing with a friend. Each of you has a penny hidden in you

Dahasolnce [82]

Answer:

a. The two players playing the game

b. No dominant strategy

c. No equilibrium

Step-by-step explanation:

a. The players are the two people playing the game of matching pennies

The strategy of the players are to meet the conditions of them keeping the pennies by having either heads or tails

The payoff of the game are as follows;

Player A keeps the two pennies when the outcome matches

Player B keeps the two pennies when the outcome does not match

The payoff of the game are as follows;

Player A

Head Tails

Player B Head 1, -1 -1, 1

Tails -1 1 1, -1

Where:

x, y

x = Player A

y = Player B

1 = Getting to keep the two pennies

-1 = Losing a penny

b. There are no best strategy because the game is one of chance whereby the result of the strategy of one player depends on the side of the penny facing up by the other player.

c. There is no equilibrium as the possible outcomes are equal hence the outcomes can be even or one sided.

in the usa, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches

Otrada [13]

Answer:

x intercept = 8

y intercept = -24

Step-by-step explanation:

In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.

When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.

Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.

To get x intercept put y=0, f = $\frac{24}{3}$ = 8 inches .

This is the point from which where we start our shoe size.

The y intercept , s = -24.

A researcher at the University of Washington medical school believes that energy drink consumption may increase heart rate. Supp

Nana76 [90]

Answer:

Step-by-step explanation:

Given that:

mean μ = 70

sample size = 25

sample mean = 73

standard deviation = 7

level of significance = 0.10

The null hypothesis and the alternative hypothesis can be computed as follows:

$\mathtt{H_o : \mu = 70} \\ \\ \mathtt{H_1 : \mu > 70 }$

The z score for this statistics can be calculated by using the formula:

$z = \dfrac{X- \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$z = \dfrac{73- 70}{\dfrac{7}{\sqrt{25}}}$

$z = \dfrac{3}{\dfrac{7}{5}}$

$z = \dfrac{3 \times 5}{{7}{}}$

z = 2.143

At level of significance of 0.10

degree of freedom = n -1

degree of freedom = 25 - 1

degree of freedom = 24

The p - value from the z score at level of significance of 0.10 and degree of freedom of 24 is:

P - value = 1 - (Z < 2.143)

P - value = 1 - 0.9839

P - value = 0.0161

Decision Rule: since P value is lesser than the level of significance, we reject the null hypothesis.

Conclusion: We conclude that energy drink consumption increases heart rate.
