Question
![To determine if Reiki is an effective method for treating pain, a pilot study was carried out where a
certified second-degree Reiki therapist provided treatment on volunteers. Pain was measured using a visual
analogue scale (VAS) immediately before and after the Reiki treatment. The data is in the table. Compute a
90% confidence level for the mean difference in VAS score from before and after Reiki treatment. Round to
three decimal places.

Interpret each interval. Does it appear that males use tobacco at a higher rate than females? Justify your answer, using the confidence intervals in your explanation. Construct the same confidence interval for males at the 99% confidence level. Compare to the male 95% confidence interval from the previous question.

- construct a confidence interval for this data. You should construct a 95% confidence interval for this data. How you do this will depend on whether your data is summarized using a mean or proportions. If you have categorical data, you will have to pick one of the categories and focus on a confidence interval for the proportion for that category, and you only need to do one for that one category. Please show the parts of your equation (point estimate, Z or T, and standard error) in addition to your final result.arrow_forwardA graduate student is interested in how viewing different types of scenes affects working memory. For his study, he selects a random sample of 36 adults. The subjects complete a series of working memory tests before and after walking in an urban setting. Before the walk, the mean score on the test of working memory was 9.1. After the walk, the mean score was 1.4 higher. The graduate student has no presupposed assumptions about how viewing different types of scenes affects working memory, so he formulates the null and alternative hypotheses as: H00 : μDD = 0 H11 : μDD ≠ 0 Assume that the data satisfy all of the required assumptions for a repeated-measures t test. The graduate student calculates the following statistics for his hypothesis test: Mean difference (MDD) 1.4 Estimated population standard deviation of the differences (s) 1.6 Estimated standard error of the mean differences (sMDMD) 0.2667 Degrees of freedom (df) 35 The t statistic 5.25 The critical values of t…arrow_forwardData are used either to test a hypothesis or to construct a confidence interval, but not both.

Use the table below to construct an 80% confidence interval for the true mean change in the typing speeds for people who have completed the typing program. Let Population 1 be the typing speed before taking the program and Population 2 be the typing speed after taking the program. Round the endpoints of the interval to one decimal place, if necessary.
