In this discussion, you will be conducting a hypothesis test using the results to your survey question. 1. State a claim that you would make related to the survey question that you asked in Discussion 1. (Imagine that you are developing this claim before you actually collected the data.) State the level of significance you would like to test your claim at. (Yes, as the researcher, you get to decide on what level you'd like to use.) 2. State the null and alternative hypotheses. Be sure to use the correct notation. 3. Find the value of the appropriate test statistic. Be sure to include the correct type and value. 4. Find the p-value. 5. State your conclusion about the null hypothesis. 6. State your conclusion about the claim.
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 67%. 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, and the alternative hypothesis H, that we would use for this test. H 0 H 0 OSO
5. A psychologist would like to examine the effects of different testing methods on the final performance of college students. One group gets regular quizzes, one group gets three large exams, and the third group only gets a final exam. At the end of the course, the psychologist interviews each student to get a measure of the student's overall knowledge of the material. a. Use a= .05. Conduct the Four Steps for Hypothesis Testing. Then, complete the table below with all the required calculations. b. Are the data sufficient to conclude that thier is a significant difference among the three methods? Write your answer in the form of a sentence. c. Conduct a Tukey's HSD to determine if there is a sigificant difference between any of the 3 groups.

Esp A college professor states that this year's entering students appear to be smarter than entering students from previous years. The college's records indicate that the mean IQ for entering students from earlier years is 110. Suppose that we want to sample a small number of this year's entering students and carry out a hypothesis test to see if the professor's statement can be supported. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H: [ O
STATE THE NULL AND ALTERNATIVE HYPOTHESES OF THE FOLLOWING. NEWBORN BABIES ARE MORE LIKELY TO BE BOYS THAN GIRLS. A RANDOM SAMPLE FOUND 12,193 BOYS WERE BORN AMONG 26,468 NEWBORN CHILDREN. THE SAMPLE PROPORTION OF BOYS WAS 0.4607. IS THIS SAMPLE EVIDENCE THAT THE BIRTH OF BOYS IS LESS COMMON THAN THE BIRTH OF GIRLS IN THE ENTIRE POPULATION?
Gun ownership. A friend claims that 33% or less Americans have a gun in their household. To test this claim, I survey 200 random Americans and find that 64 of them have a gun in their household. What should I conclude about my friend's claim?(a) Select the correct null and alternative hypotheses. Ho: p = 0.33Ha: p > 0.33 Ho: p = 0.33Ha: p < 0.33 Ho: p = 0.33Ha: p ≠ 0.33 Ho: p = 0.32Ha: p > 0.32 Ho: p = 0.32Ha: p ≠ 0.32 Ho: p = 0.32Ha: p < 0.32 (b) Find the p-value (round to three significant figures). (c) Write the final conclusion using everyday language using a 5% level of significance. There is not sufficient evidence to reject my friend's claim. There is sufficient evidence to reject my friend's claim. There is sufficient evidence to support my friend's claim. There is not sufficient evidence to support my friend's claim.
A man is on trial accused of murder in the first degree. The prosecutor presents evidence that he hopes will convince the jury to reject the hypothesis that the man is innocent. This situation can be modeled as a hypothesis test with the following hypotheses: Explain the meaning of a Type I error.
1. Explain the concept of a hypothesis test, and why it is used in research and science. 2. Conduct a hypothesis test, by executing the following steps: a. Identifying the correct type of test. b. Creating the two hypotheses. c. Organizing the information from the problem. d. Calculating any missing statistics. e. Finding the P-value on your calculator. f. Making the decision of the test. g. Writing a sentence which embodies your decision. 3. Differentiate between a 1-sided and 2-sided test. 4. Differentiate between a 1-proportion z-test and 2-proportion z-test.
I. Do the following: a. State the null and alternative hypotheses, identify which represents the claim, b. Determine when a type I or type II error occurs for a hypothesis test of the claim. c. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning. d. Explain how you should interpret a decision that rejects the null hypothesis. e. Explain how you should interpret a decision that fails to reject the null hypothesis. Problem. II. Conduct a hypothesis test A research center claims that less than 50% of senior high school students in public schools in the Philippines have accessed the Internet using cellular phones. In a random sample of 100 SHS students, 39% say they have accessed the Internet using cellular phones. At = 0.01, is there enough evidence to support the researcher’s claim?
