3. As we have seen in class, hypothesis testing, and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all the following:
a. A detailed discussion of your experimental design. Detailed experimental design should include the type of experiment, how you chose your sample size, what data is being collected, and how you would collect that data.
b. How is randomization used in your sampling or assignment strategy? Remember to discuss how you would randomize for sampling and assignment, what type of randomization are you using?
c. The type of inferential test utilized in your experiment. Include type of test used, number of tails, and a justification for this choice.
d. A formal statement of the null and alternative hypothesis for your test. Make sure to include correct statistical notation for the formal null and alternative, do not just state this in words.
e. A confidence interval for estimating the parameter in your test. State and discuss your chosen confidence level, why this is appropriate, and interpret the lower and upper limits.
f. An interpretation of your p-value and confidence interval, including what they mean in the context of your experimental design. Answer each part below. State your significance level, interpret your p-value, and make a decision on the null.

Research is an integral part of all professional fields. Designing a research study can be a complicated task that can be simplified if the appropriate techniques can be identified. This assignment will give you the opportunity to design an experiment, including finding relevant prior research, determining the appropriate sample, data analysis techniques, and discuss the results you hope to see. Working from the topic chosen earlier in the topic selection, you will be designing your own statistical study. In a...

O CONFIDENCE INTERVALS AND HYPOTHESIS TESTING Hypothesis test for a population proportion Lau A decade-old study found that the proportion, p, of high school seniors who beleved that "getting rich" was an important personal goal was 70%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 220 high school seniors in his random sample, 135 beleve that "getting rich" is an important goal. Can he conclude, at the 0.1 level of significance,...

Confidence interval and hypothesis testing are commonly used in business (and other fields) to make decision(s) from data. For this assignment, find a journal or article that have used confidence interval(s) and/or hypothesis test(s) to make decision(s) or conclusion(s). In your post, include: (a) a brief summary of the journal/article; (b) how confidence interval(s) or hypothesis test(s) were used; and (c) decision(s) and/or conclusion(s). Be sure to cite the journal/article you've used. For peer responses, discuss the similarities and/or differences...

What is a confidence interval? (c) A poll service indicates that 74% of the public is opposed to a certain piece of legislation but there is a 95% margin of sampling error of 3.1%. Express these findings as a confidence interval. (d) You read in the paper that in a...

On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on ? = 5 UAVs (all of the new type) resulting in a sample mean dwell time of ?1 = 10.4 h????. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10...
