Answer:

D. We are 95% confident that the proportion of all Americans who say that race relations in this country are generally bad is between 58% and 64%.

Step-by-step explanation:

The 95% confidence interval refers that 95% of data is correct with respect of the population

Given that 95% confidence interval is (0.58, 0.64)

So based on this, the option D is correct as it shows the right thing with regard to 95% confidence interval

Therefore all the other options are incorrect as the first option is of probability, the second option is the sample, and the third option is of statement form i.e not standardized.

Levart [38]
Right now it is noon..... you are traveling 75 miles per hour meaning you'll move 75 miles... every hour. so you're 120 miles away so now we need to figure out the time.... to do this we already know 1 hour is 75 miles so now you can subtract one hour 120-75= 45 so 75 per hour, what would 45 be?..... so we can set up a fraction to figure out how long it takes to travel one minute.... so 60/75(the 60 is for minutes in an hour). which is .8 of a second to travel one mile so.... now you can multiply to check your work. .8*75=60 mins.... so now multiply.8*45(miles left)=36 so you'd get there at 1:36 it would take an hour and 36 mins to get to your destination going 75mph
