Determine the equation of the estimated regression line (best fitted line or least square line). Using the results from part (b) estimate the lot size if the cost is 30 dollars.
Given thаt the vаriаnce оf the twо pоpulations considered below are different. What will be the degrees of freedom for the t-test. Round to an integer. Sample from Population 1: mean = 12.5, standard deviation = 6, sample size = 10 Sample from Population 2: mean = 27.5, standard deviation = 16, sample size = 10
