Explanation Given info: The data shows that the fuel efficiency for hybrid and electric cars (in miles per gallon gasoline equivalent) ( x ) and the top speeds for hybrid and electric cars (in miles per hour) ( y ) values. Also, the combined city and highway fuel efficiency is 90 miles per gallon equivalent and the given confidence level is 99%. Calculation: Prediction interval: Software procedure: Step-by-step procedure to obtain the ‘Prediction interval’ using the MINITAB software: Choose Stat > Regression > Regression > Options . In Response , enter the column containing the Top speed. In Predictors , enter the columns containing the Fuel efficiency . In Prediction intervals for new observations , Type numeric predictor value as 90...

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance
