- Suppose that the population in question is the set of all registered voters in the Philippines. A rough estimate of the total number of registered voters is 90,000,000. Calculate the random samples where the error of tolerance is 0.01%
- In a survey on the level of awareness of registered voters registered voters regarding the computerization of the election processes resulted into:
|
(5) |
(4) |
(3) |
(2) |
(1) |
|
|
Strongly Agree |
Agree |
Undecided |
Disagree |
Strongly Disagree |
|
|
Level of Awareness |
800 |
200 |
50 |
100 |
50 |
compute the mean and interpret the results.
Homework Answers
Total level of awareness = 800+200+50+100+50 = 1200
Arranging the data we get
| strongly agree | agree | undecided | disagree | strongly disagree | |
| x | 5 | 4 | 3 | 2 | 1 |
|
P(x) Level of Awareness |
800/1200 | 200/1200 | 50/1200 | 100/1200 | 50/1200 |
Mean = sum(Pi*Xi)
= 800/1200 * 5 + 200/1200 * 4 + 50/1200*3 + 100/1200 *2 + 50/1200* 1
= 800/1200 * 5 + 200/1200 * 4 + 50/1200*3 + 100/1200 *2 + 50/1200* 1
= 4.33
Thus, mean indicate that average level of awareness is between agree and strongly agree, and is inclined towards agree

This problem demonstrates how to calculate the confidence interval for a population proportion. After, you will be asked to redo the calculations (with small variations). A survey was conducted to determine how many people were in favor of a proposed law to criminalize texting while driving. Response options included strongly disagree, disagree, neither agree or disagree, agree, and strongly agree. The survey asked a random sample of 800 18- to 25-year-olds, and 648 indicated agreeing or strongly agreeing with the...

3. The teachers union is concerned about the amount of time teachers spend each week doing schoolwork at home. A simple random sample of 56 teachers had a mean of 8.0 hours per week working at home after school. Assume that the population standard deviation is 1.5 hours per week. a) Construct a 95% confidence interval estimate for the mean number of hours per week a teacher spends working at home. b) Does the confidence interval support...

Question 41 2 pts A software company is developing a new computer game. The manager wants to know what effect the frequency at which opponents are released by the computer has on the length of time players survive in the game. A large group of playtesters is available, most of whom already have some experience playing the new game, and each is randomly allocated to play the game with a different opponent release frequency Data was collected for the variables...
