3. Open Roof or Closed Roof? In a recent World Series, the Houston Astros wanted to close the roof on their domed stadium so that fans could make noise and give the team an advantage at home. However, the Astros were ordered to keep the roof open unless weather conditions justified closing it. But does the closed roof really help the Astros? The table below shows the results from home games during the season leading up to the World Series. Use a 0.05 significance level to conduct a Chi-Square Test for Association. Is there sufficient evidence to show that there is a relationship between wins and the open/closed status of the roof?
| Win | Loss | |
| Closed Roof | 36 | 17 |
| open Roof | 15 | 11 |

Solutions
Expert Solution
Chi-Square Test for Association is Chi-square independence in hypothesis testing .
We conclude that there is a no relationship between wins and the open/closed status of the roof.

2. A circuit contains 3 resistors connected in series and no
battery. It is a closed circuit and has dimensions of 18 cm by 42
cm. The resistor values are 12, 15 and 18 ohms. A magnetic field
directed out of the plane of the circuit changes from 52 T to 0 T
in 2.9 sec.
a. Sketch the circuit and indicate the direction of the initial
magnetic field.
b. What is the magnetic flux through the circuit when the...

3. In recent days, governments around the world are seeking to
extend retirement age as the productive segment of workers are
approaching decline in an aging demographic. In personal wealth
planning, individuals focus on the time horizon for short-term,
intermediate-term, and long-term goals. Postulate the outcome in
the imposition of such policies and its outcome. How can
individuals cope with changes in such policy changes? (300
