Hello. Could anyone help me on this question? I have tried it four times and only one attempt left. What I am confusing is that some choice are not individual and variables. Like all young children, children who eat snack and cartoon characters. But if i leave them there, it shows me I am wrong. Pls help me on this and explanation would be appreciated. Thanks!
A researcher is wondering whether the drinking habits of adults in a certain region of a country are different than those in the general adult population. Suppose a recent study states that the proportion of adults in the general population who reported drinking once a week or less in the last month is 0.26. The null hypothesis for this test is p = 0.26 and the alternative hypothesis is p+ 0.26. The researcher collected data from 150 surveys he handed out at a busy park located in the region. Are the conditions for proceeding with a one-proportion z-test satisfied? If not, which condition is not satisfied? O a. Conditions are not satisfied; the researcher did not collect a random sample. O b. Conditions are not satisfied; the population of interest is not large enough to assume independence. Oc. Conditions are not satisfied; the sample size is not large enough. O d. All conditions are satisfied.
section 10.2 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?
Answer D
A sociologist wants to study what proportion of people have significant relationship problems due to financial stress. A previous study she is aware of estimated it to be 32% but she believes this has increased in modern times. She collects a random sample of 150 people and 63 of them report relationship problems due to financial stress. Conduct an appropriate hypothesis test in questions #22-#25. Compute the Z-score for this hypothesis test and round to two decimal places. z = 1.58 z = 2.06 z = 2.63 z = 0.84
Question #10 Please explain The three principles of designing experiments are to control, randomize, and replicate. Which of the following statements is not true about these important principles? Considering (controlling) more variables in planning an experiment helps ensure each study group is similar to the other study groups. Using a control group with a placebo is important since otherwise folks in the control group may behave differently than those in the treatment group. Randomizing individuals into groups is one component to prevent accidental bias from creeping into a study. We can always generalize the result of a study to the greater population so long as we randomize which patients go into which study groups. Studying many cases (e.g. including many patients in a study) is often more helpful than just including a few cases in the study. If we collect more information on each case (e.g. take repeated measurements on each individual) that might be helpful to obtaining more…

In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing. For each problem students will write out all steps of hypothesis testing: 1. State the null and research hypotheses. 2. Set the level of risk associated with the null hypothesis. 3. Select the appropriate test statistic. 4. Compute the test statistic value (called the obtained value). 5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic. 6. Compare the obtained value and the critical value. 7. Make your decision. After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language 3. A psychologist has developed a standardized test for measuring the vocabulary skills of 4-year-old children. The scores on the test form a normal distribution with μ = 72 and σ = 12. A researcher would like to use this test to…
