1. Which of the following is the proper interpretation of the slope? a) For cvcry onc dollar incrcasc in Salcs, Tcmpcraturc will incrcasc on avcrage by 18.53 degrces. b) Whcn the Salcs arc 0 dollars, Tcmpcraturc will bc 18.53 degrccs, on avcrage. c) When the Temperature is 0 degrees, Sales will be 18.53 dollars, on average. d) For every one degree increase in Temperature, Sales will increase on average by 18.53 dollars. 2. What is the correlation between these two variables? a) R=-0.6862944 b) R=0.6862944 c) R=0.221841 d) R=-0.221841 3. The range of the variable Temperature that you observed was 72 F - 100 F. You hear a weather report saying a massive hcat wave is coming your way and the high in your town will bc 120°F tomorTow. You decide that you would like a prediction of your salcs tomorrow since you presume you will make so much moncy. You usc your regression cquation to predict your salcs for tomorrow and get a predicted valuc of $1461. What crror have you made? a) restricted range problem b) extrapolation c) misusc of cause and cllect d) misinterprctation of the slope and intercept

1. Which of the following is the proper interpretation of the slope? a) For evcry onc dollar incrcasc in Salcs, Tempcraturc will incrcasc on avcragc by 18.53 dcgrccs. b) Whcn the Salcs arc 0 dollars, Tcmpcraturc will bc 18.53 dcgrecs, on averagc. c) When the Temperature is 0 degrees, Sales will be 18.53 dollars, on average. d) For every one degree increase in Temperature, Sales will increase on average by 18.53 dollars. 2. What is the correlation between these two variables? a) R--0.6862944 b) R 0.6862944 c) R-0.221841 d) R=-0.221841 3. The range of the variable Temperature that you observed was 72 F - 100°F. You hear a weather report saying a massive hcat wave is coming your way and the high prcdiction of your salcs tomorrow since you presume you will makc so much moncy. You usc your regression cquation to predict your salcs for tomorrow and get a predicted valuc of $1461. What crror have you made? your town will be 120°F tomorrow. You decide that you would likc a a) restricted range problem b) extrapolation misuse of cause and cffect c) d) misinterprctation of the slope and intercept

You collected data every day last summer while working for an ice cream company about the temperature (in °F) and sales (in dollars) for that day as a way to rcscarch for your new business. You decided to fit a regression linc and gct the following bascd off of your data Sales = -762 + 18.53*Tcmpcrature R =47.1%
