Do oddsmakers believe that teams who play at home will have home field advantage? Specifically, do oddsmakers give higher point
anygoal [31]

Complete question is;

Do oddsmakers believe that teams who play at home will have home field advantage? Specifically, do oddsmakers give higher point spreads when the favored team plays home games as compared to when the favored team plays away games?

Two samples were randomly selected from three complete National Football League seasons (1989, 1990, and 1991). The first sample consisted of 50 games, where the favored team played in a home game, while the second sample consisted of 50 games, where the favored team played in an away game. The oddsmakers’ point spreads (which are the number of points by which the favored team is predicted to beat the weaker team) were then collected.

If µ1 and µ2 represent the mean point spread for home games and away games, respectively, which of the following is the appropriate.

A) H0: μ1 - μ2 = 0

Ha: μ1 - μ2 < 0

B) H0: μ1 - μ2 = 0

Ha: μ1 < μ2

C) H0: μ1 - μ2 > 0

Ha: μ1 - μ2 = 0

D) H0: μ1 - μ2 = 0

Ha: μ1 - μ2 > 0

E) None of the above

Answer:

D) H0: μ1 - μ2 = 0

Ha: μ1 - μ2 > 0

Step-by-step explanation:

We want to find out if oddsmakers give higher point spreads when the favored team plays home games as compared to when the favored team plays away games.

Now, since µ1 and µ2 represent the mean point spread for home games and away games, respectively;

It means we want to find out if µ1 > µ2 as the alternative hypothesis.

Thus, alternative hypothesis is;

Ha: µ1 - µ2 > 0

Meanwhile null hypothesis assumes that equal point spreads are given when the favored team plays home games as well as when the favored team plays away games.

Thus, null hypothesis is;

H0: μ1 - μ2 = 0

The only correct option is D.

Opinions please! Get Points! Im doing a research paper in school for English (and part math) and my topic is "Is NASA a Waste of
Irina-Kira [14]

The thing with nasa is that when they use money to build and land things such as space rovers or space shuttles, the money that is used is put back into the economy instead of just floating in space. So the idea that its a waste could easily be debunked by the fact that the money that is used is still in the economy, whether or not you believe the exploration of space is needed could also be a solid point for your paper. Hope that I could help, Good luck with your paper

Sveta_85 [38]

Answer:

<u>Usain Bolt's average speed in yards per second was 11.4</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

World record of Usain Bolt = 9.589 seconds

Distance of the world record = 100 meters

1 yard = 0.9144 meters ⇒ 100 meters = 109.36 yards

2. What was Usain Bolt's average speed in yards per second?

Let's recall that the formula of speed is:

Speed = Distance/Time

Replacing with the values we know:

Usain Bolt's Speed = 109.36/9.589

<u>Usain Bolt's Speed = 11.4 yards per second (Rounding to one decimal place)</u>

-Subtract and simplify -y^2-3y-5)-(x36^2-7y+4
AnnZ [28]

Answer:

-y^2 - 10 y - x^72 + -1

Step-by-step explanation:

Simplify the following:

-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4

Multiply exponents. (x^36)^2 = x^(36×2):

-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4

36×2 = 72:

-y^2 - 3 y - 5 - x^72 - 7 y + 4

Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):

-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)

-3 y - 7 y = -10 y:

-y^2 + -10 y - x^72 + (4 - 5)

4 - 5 = -1:

Answer: -y^2 - 10 y - x^72 + -1
