You notice that the sticker of a 2014ford explorer states that it gets 18 miles per gallon city driving. a random sample of 30 2014ford explorers had the following miles per gallon per city driving. 19.318.1 17.317.3 18.519.3 15.816.4 18.216.4 16.418.0 16.717.6 18.118.6 17.717.6 17.318.6 15.616.915.516.0 18.217.9 16.218.4 17.417.0 is there sufficient statistical evidence to conclude that2014ford explorers get less than 18 miles per gallon city driving? explain your answer. hint: think, calculate the p value

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
