Which of the following is an unbiased estimate for the population proportion of high school graduates in Honolulu?
The number of high school graduates among a random sample of UH students
The fraction of high school graduates among a random sample of UH students
The fraction of high school graduates among a random sample of Honolulu residents
The number of high school graduates among a random sample of Honolulu residents
Homework Answers
First of all it is asking for 'population proportion' so it cannot be number of high school graduates because those are actual numbers not proportion.
Next, UH students does not reflect a good estimate of true population for Honolulu
Hence, Option C) The fraction of high school graduates among a random sample of Honolulu residents
is an unbiased estimate for the population proportion of high school graduates in Honolulu.

A report says that 82% of British Columbians over the age of 25 are high school graduates. A survey of randomly selected residents of a certain city included 1290 who were over the age of 25, and 1135 of them were high school graduates. Does the city's survey result provide sufficient evidence to contradict the reported value, 82%? Part i) What is the parameter of interest? A. The proportion of 1290 British Columbians (aged above 25) who are high school...

15. (8 points) An educator desires to estimate, within 0.03, the true proportion of high school students who study at least 1 hour each school night. He wants to be 98% confident. (a) How large a sample is necessary? Previously, he conducted a study and found that 60% of the 250 students surveyed spent at least 1 hour each school night studying. (b) If no estimate of the sample proportion is available, how large should the sample be?
