Answer:
d. will always be unbiased.
Step-by-step explanation:
When some of variables are omitted the estimator on indulge charge regressor may still be unbiased. If there is a special case where T = 2 then the FE estimator will be unbiased. Fixed effect regression model has different intercepts.

The correct answer is 8.
The ratio of boys to girls is 5:7. 5 + 7 = 12 5/12 of the students are boys. 7/12 of the students are girls. The number of boys is (5/12)48 = 20. The number of girls is (7/12)48 = 28. 28 - 20 =8. Therefore, there are 8 more girls than boys in the play.

Answer: 157 ft
Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is shown below.
Circumference = 2πr
Notice that the circle has a radius of 25 feet. So we can plug in 25 feet for <em>r</em> in the formula. So we have (2)(π)(25 ft) which is equal to 50π ft.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (50)(3.14) which is equal to 157.
So the circumference of the circle is approximately equal to 157 ft.
