Asocial scientist would like to analyze the relationship between educational attainment (in years of higher education) and annual salary (in $1,000s). he collects data on 20 individuals. a portion of the data is as follows:
education 3 4 6 2 5 4 8 0
salary $40 36 56 35 72 47 107 52
a) find the sample regression equation for the model: salary = ? 0 + ? 1education + ? . (round intermediate calculations to 4 decimal places. enter your answers in thousands rounded to 2 decimal places.)
b) interpret the coefficient for education.
c) what is the predicted salary for an individual who completed 7 years of higher education? (round intermediate coefficient values to 2 decimal places and final answer, in dollars, to the nearest whole number.)

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.

Can anyone me with this question?
