A savvy egg quality forecaster develops a linear model using the transformation X 2 = (Haugh Units) 2. Which of these statements about the equation Ŷ = 15.2-7X 1 -3.5X 2 is best? Y = The curvature of the relationship is more important than the linear component. Y = The intercept term in the model is twice as important at the value of the Haugh Units. Haugh Units have twice the impact as Haugh Units squared. We should not try to interpret the coefficients of the variables due to the correlation between X1 and X2

You paid 28.00 for 8 gallons of gasoline. how much would you pay for 15 gallons of gasoline?

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
