how to I solve a using single linear Regression in excel or any excel method? I am struggling to understand this question. Can please be very detailed about it, how you were able to do so and what you used to get these answers. I struggle to understand how to answer to this question below. An agent for a real estate company in a suburb has the business objective of developing more accurate estimates of the monthly rental cost for apartments. The agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent collects data from a sample of 30 one-bedroom apartments. b. Construct a 95% prediction interval estimate of the monthly rental for all one-bedroom apartments that is 810 square feet in size. _____≤μYX=810≤______(Type integers or decimals.

Q2 (a)State in algebraic notation and explain the assumption about the classical linear regression models disturbances that are referred to by the term ‘homoscedasticity’. (b)What would the consequence be for a regression model if theerrors were not homoscedastic? (c) How might you proceed if you found that (b) were actually the case? (d) What do you understand by the term ‘autocorrelation’?

The high p-value and low coefficient of determination indicate that the equation is inadequate. The high p-value and high coefficient of determination indicate that the equation is adequate. The low p-value and low coefficient of determination indicate that the equation is inadequate. The low p-value and high coefficient of determination indicate that the equation is adequate. to two decimal places and b₁ to three decimal places and b₂ to four decimal places.)

Can you discuss the potential pitfalls of this scenario? The regression equation based on data from years 1 thru 10 is, y = 6 + 32 x Where, X = Year We want to forecast a result in year 20, i.e. find value of y when x = 20 Solution : The forecast result in year 20 is, y = 6 + (32)*(20) y = 6 + 640 y = 646 The forecast result in year 20 is 646.
