Fuel economy estimates for automobiles built in a certain year predicted a mean of 27.8 mpg & a standard deviation of 5.2 mpg for highway driving. Assume that a normal distribution can be applied. Within what range are 95% of the automobiles?

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

it would take 7/10 of an hour too fill the pool.
