-There is a 99% chance that the proportion of coupon users in a sample of 87 students will be between 0.14 and 0.24.
-There is a 99% chance that the proportion of the population is between 0.14 and 0.24.
-With 99% confidence, the proportion of constumers who use coupons is between 0.14 and 0.24.

PART 2

The nurses at Phoenix Children's Hospital were chosen this year to vote on the theme of the annual Children's Dance. There are 600 nurses at PCH. The themes chosen for this year are: Alice in Wonderland or How Sweet it is. The day before the offical vote, a telephone poll of 100 randomly selected nurses was conducted. 49 said they'd vote for Alice in Wonderland, 43 said they'd vote for How Sweet it is, and 8 were undecided.

Give the sample statistic for the proportion of voters surveyed who said they'd vote for Alice and Wonderland.  Note: The proportion should be a decimal to two places, not a percent.

    
This sample statistic suggests that we might expect BLANK of the 600 registered voters to vote for Alice and Wonderland.
