please help me with this problem. thank you.

1. (Wage Regression) A researcher is using data for a sample of 3,240 female employees 25 years of age and over to investigate the relationship between employee's hourly wage rates, Y; (measured in dollars per hour) and their age X1- (measured in years). The population regression equation takes the form of equation (1): Y=o +131X4+Ui (1) Preliminary analysis of the sample produces the following sample information: N N N N = 3240, 207217? = 78434.97, ZoeX)? = 25526.17, Z(X.-X)(Y.1?) = 3666.436 {:1 i=1 i=1 N N N Z Y,- = 34379.16, 2X, = 96143.00, 2 1/3 = 443227.10 i=1 1 N N N Z X,? = 287845100, 2 X,Y,- = 102382500, 2 6,? = 77908.35 11:1 11:1 \"i=1 Use the above information to answer all of the following questions.
