  2. Project Questions

  3. Dart Throw Review • Students will be split up into groups of 4-5. • Each student will be assigned a letter A-E. • All students are responsible for backing up their answers on their own sheet of paper. • When a letter is called, that group member must present their work to a teacher. • If the student is correct and has shown all work, then they will put a tally mark next to their team name. • If the student is incorrect, they will no receive a tally mark and the group must correct their work. • After a few rounds of questions, students will throw darts on the board for points.

  4. Dart Throw Scoring Board • -20 points if the dart does not land inside the square or if it falls on the ground • No points if the dart lands in the white region 100 50 30 70 100 50 30 30 20 20 70 20 10 20 20 10 30 20 50 100 50 30 70 10 50 20 10 100 30 10 30 20 10 20 20 20 70 50 100 100 50

  5. Question 1 Identify the null and alternative hypothesis. An entomologist writes an article in a scientific journal which claims that fewer than 7 in ten thousand male fireflies are unable to produce light due to a genetic mutation. p= 0.0007 p< 0.0007

  6. Question 2 Identify the null and alternative hypothesis. Carter Motor Company claims that its new sedan the Libra, will average better than 26 miles per gallon in the city. However, a recent study of 500 Libras found an average of 24 miles per gallon. = 26 > 26

  7. Question 3 Identify the null and alternative hypothesis. A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is 0.03%. While a study of 32 people showed that 0.01% of the respondents had seen a UFO. p = 0.0003 p 0.0003

  8. Dart Throw Scoring Board • -20 points if the dart does not land inside the square or if it falls on the ground • No points if the dart lands in the white region 100 50 30 70 100 50 30 30 20 20 70 20 10 20 20 10 30 20 50 100 50 30 70 10 50 20 10 100 30 10 30 20 10 20 20 20 70 50 100 100 50

  9. Question 4 Test the given claim. A random sample of 100 pumpkins is obtained and the mean circumferences is found to be 40.5 cm. Assuming that the population standard deviation is known to be 1.6cm, use a 0.05 significance level to test the claim that the mean circumference of all pumpkins is equal to 39.9 cm. Reject the null hypothesis. There is sufficient evidence to reject Our sample data suggests the mean circumference of all pumpkins is not equal to 39.9 cm.

  10. Question 5 Test the given claim. In Oswego, monthly incomes for men with college degrees was found to have a standard deviation of $650. Use a 0.01 significance level to test the claim that for men without college degrees in Oswego, incomes have a higher standard deviation. A normally distributed random sample of 22 men with college degrees resulted in incomes with a standard deviation of $926. Reject the null hypothesis. There is sufficient evidence to reject . Our sample suggests the standard deviation is greater than $650.

  11. Question 6 Test the given claim. A light-bulb manufacturer advertises that the average life for its light bulbs is 900 hours. A normally distributed random sample of 15 of its light bulbs resulted in the following lives in hours: 995, 590, 510, 539, 739, 917, 571, 555, 916, 728, 664, 693, 708, 887, 849 Test the claim at 0.01 significance level. Reject the null hypothesis. There is sufficient evidence to reject Our sample suggestions the mean life in hours is not equal to 900.

  12. Question 7 Answer The Following: What should you do if you read a problem and the requirements for the section it is in are not met? Answer Not Possible – Requirements Not Met.
