Answer:

A. The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

The first equation is y = b_0 + b_1x , this is the equation for sample data as the intercept (b_0) and the slope parameter(b_1)  both are calculated then we have got this and these values are not taken as given.

The Second equation is y = \beta _0 +\beta _1x , this is the equation for population data as we can't calculate these \beta _0 and \beta _1 as we take these values as given and also we do testing for \beta parameter using t test and it is sure that testing is always done on population data not on sample data.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile
Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where  d represents the distance, that the car travels at this speed in t  at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.
