We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.

In a test of the effectiveness of garlic for lowering cholesterol, 50 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 5.8 and a standard deviation of 17.3. Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. WWhat does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? Click here to view a t distribution table.

Á study was conducted that examined the relationship between alcohol consumption and risk of heart attack. In all, 417 men, age 40 or older, were tracked over ten years and the number of that experienced a heart attack was recorded. The participants were grouped by those who totally abstained from alcohol and those that drank moderately. For the results given in the table below, use the chi-squared test to find the p value for NHST at the .05 level. (In SPSS use the Yates continuity correction value.)

Individual scores for practices towards COFLU-20 are found to be normally distributed with a mean of 3 and a standard deviation of 1.5 over the entire population. The Ministry of Health wishes to use this information to identify individuals whose score on practices towards COFLU20 is in the lower 75%, in order to give them relevant information on the best practices towards COFLU-20. You are asked to assist in calculating the score that the Ministry of Health should use to decide whether an individual should be given the relevant information?
We have presented a confidence interval (CI) for the difference, μ1 − μ2, between two population means. Interpret each confidence interval. 99% CI is from −10 to 5.
National Cookie Company produces premium chocolate chip cookies for sale in up-scale food markets. Cookies are sold in 250 gram packages of 10 cookies. Unfortunately, the manufacturing process has some inherent variation. After years of improving the process, National has reduced the standard deviation of the process to 0.6 grams per cookie. In the short term, the variation of 2 the production process is outside National’s control. However, National is able to adjust the mean weight level for each cookie. For various economic reasons, setting the mean level properly is important. If it is too high, then the cookies are heavier than required and National must incur unnecessarily high raw material costs; if the mean level is too low, then the cookies must be sold as thrift. a) Assume that National sets the maximum number of underweight packages at 2.5%. Where should National set the mean weight level per cookie?
Select all of the assumptions that you need to make when creating a confidence interval on the difference between means. At least 2% of the population sampled Independently sampled values Homogeneity of variance Normally distributed populations?
A trial study suggest that the standard deviation for the half life for the drug chlordiazepoxide is 8 hours. With 99% confidence, find the sample size needed to determine the mean half life for the drug with a margin of error of 3 hours.
Preliminary analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers obtained the following data on the number of acute postoperative days in the hospital using the dynamic and static systems. Obtain a 90% confidence interval for the difference, μ₁ −μ₂, between the mean numbers of acute postoperative days in the hospital with the dynamic and static systems. (Note: x₁ = 7.42, s₁ = 1.38, x₂ = 11.67, and s2 = 4.68) The 90% confidence interval is from to (Round to three decimal places as needed.) 8 7 10 Dynamic 4 8 7 8 60 00 8 8 Static 14 6 8 9 13 7 9 19
The design of controls and instruments affects how easily people can use them. A student project investigated this effect by asking 25 right handed students to turn a knob with their right hands that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread and the other with a left-hand thread. The table given has the data from the student project.1. Calculate and interpret a 90% confidence interval for the mean time advantage of right hand over left hand threads in the setting above.
The NCHS reported that the mean total cholesterol level was 203 for all adults in 2003. Patients (n=15) were enrolled in a 6-week study to test the efficacy of a new drug. Use the five-step hypothesis testing procedure to determine if the new drug was effective in reducing the cholesterol levels compared to the historical mean. At the end of 6 weeks: ◦n = 15 ◦X ̅ = 195.9 ◦s = 28.7
