Suppose you run two regressions on data that are the same up to units:
1) Regression of wage (measured in dollars per hour) on years of education.
2) Regression of wage (measured in cents per hour) on years of education.

What is the relationship between the estimated coefficients in regressions 1) and 2)? Formally justify your answer.

The table above shows approximate conversions from gallons to liters. what is the value of x?

Solve the equation below: (x+4)/6x=1/x a. x=2 b. x=0,2 c. x=-2 d. x=0,-2

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
