Q:

1.   1,020 randomly selected adults were asked whether they took statistics class. Only 45% said ‘yes’.

a.   What percent did not respond ‘yes’?

b.   Is the proportion answering ‘yes’ (45%) a parameter or a statistic? Explain your answer.

c.   Find a range for the number of people who responded ‘yes’. That is, determine all the numbers that, when divided by 1,020, round to 0.45.

(Note: 0.45 x 1020 = 459. But if you try 458 divided by 1,020, or 460 divided by 1,020, you will also get 0.45 to two decimal places. Which other values meet this criterion?)

 

You must SHOW ALL WORK.
