Need answer to question 12.
Kenya is a behavioral psychologist who works with children on the Autism Spectrum. She suggests that blowing bubbles may effect children's eye contact (she hasn't predicted if it would increase or decrease). She works with a student who makes 5 points of eye contact in a session. How would the NULL hypothesis be state for her study using bubbles? µ < 5 µ = 5 µ > 5 µ ≠ 5
A decade old study found that the proportion of high school seniors who felt that getting rich was an important personal goal was 69%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H o and the alternative hypothesis H 1 that we would use for this test. H o: H 1:
9 Question 4 A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every bag contains exactly the same weight. But if more than 16% of bags are over-filled then they stop production to fix the machine. They define over-filled to be more than 1 ounce above the weight on the package. The engineer weighs 129 bags and finds that 27 of them are over-filled. He plans to test the hypotheses Ho: p = 0.16 versus H:p> 0.16. What is the test statistic? Z = (Please round your answer to two decimal places if necessary.)
QUESTION 1 If the alternate hypothesis states that p # 4,000, where is the rejection region for the hypothesis test? O 1. In the lower or left tail O 2. In the center O 3.

section 10.3 Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below. Step 2 of 3 : Compute the value of the test statistic. Round your answer to three decimal places. Step 3 of 3: Do we reject the null hypothesis? Is there sufficient or insufficient data?
part a is identifying the claim and stating H0 & Ha.
In each problem show all steps of the hypothesis test using PHANTOMS. If some of the assumptions are not met, note that the results of the test may not be correct and then continue the process of the hypothesis test. The Kyoto Protocol was signed in 1997, and required countries to start reducing their carbon emissions. The protocol became enforceable in February 2005. In 2004, the mean CO2 emission was 4.87 metric tons per capita. Table 7.3.3 contains a random sample of CO2 emissions in 2010 ("CO2 emissions," 2013) from 30 countries. Is there enough evidence to show that the mean CO2 emission is lower in 2010 than in 2004? Test at the 1% level. Table #7.3.3: CO2 Emissions (in metric tons per capita) in 2010 1.36 1.42 5.93 5.36 0.06 9.11 7.32 2.86 7.93 6.72 0.78 1.80 0.20 2.27 0.28 2.44 5.86 3.46 1.46 0.14 2.62 0.79 7.48 0.86 7.84 2.87 2.45 5.85 3.45 1.45
Question 29 If the p-value is less than alpha in a one-tail test, what decision can you make? O A two-tail test should be used. O The null hypothesis should not be rejected. O Alpha should be changed. O The null hypothesis should be rejected.
