Captopril is a drug designed to lower systolic blood pressure. Systolic blood pressure was measured for six men before and after the drug was administered. The results, in mm of mercury, appear in the table below.

A random sample of monthly gasoline prices was taken from 2005 and from 2011. For 2005, it shows that the average gasoline price was $2.01 with a standard deviation of $1.07. For 2005, it shows that average gasoline price was $3.35 with a standard deviation of $1.32. Can it be concluded that the mean gasoline cost less in 2005?What will be the appropriate statistical analysis to use in this problem? a. t-Test for Comparing Two Means from Independent Samples b. z-test for comparing the difference between two proportions c. t-Test for Comparing Two Means when the Samples are Dependent d. z-Test for Comparing Two Means from Independent Populations e.

For all students who have taken a certain class during the last ten years, theaverage on the mid-term is 83.4 and the standard deviation of the mid-termscores is 7.2; the average on the final is 79.3 and the standard deviation of thescores on the final is 5.1; the correlation between scores on the mid-term andscores on the final is 0.86. 4. My teacher has lost our mid-term scores (but at least has our scores onthe final), so she is fitting a straight line to guess what we probably got onthe mid-term. What’s the equation of the line she is using? 5. I got a 90 on the final. What does my teacher think I got on the midterm?
A researcher would like to know how much physical endurance is affected by a common herbal supplement. The researcher measures endurance for a sample of n = 9 participants. Each is then given a 30-day supply of the herbs and, one month later, endurance is measured again. For this sample, endurance increased by an average of MD= 6 points with SSD = 216. a. make a point estimate of the mean difference in endurance after taking the herbs. b. make a 95% confidence interval estimate of the population mean difference.
You want to buy a washing machine, and a salesperson tells you that the mean repair costs for Model A and Model B are equal. You research the repair costs. The mean repair cost of 21 Model A washing machines is $215. Assume the population standard deviation is $19. The mean repair cost of 22 Model B washing machines is $221. Assume the population standard deviation is $20. At α=0.01, can you reject the salesperson's claim? Assume the samples are random and independent, and the populations are normally distributed.
A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. Before starting the trial, a pilot study is conducted involving eight participants. The objective of the study is to assess how systolic blood pressure changes over time untreated. Systolic blood pressures are measured at baseline and again 4 weeks later Is there a statistically significant difference in blood pressures over time? Run the test at a 5% level of significance. Give each of the following to receive full credit: 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.

A certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 33 students' scores on the exam after completing the course: −6,11,18−6,11,18 Using these data, construct a 90%90% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal. Copy Data Step 4 of 4 : Construct the 90%90% confidence interval. Round your answer to one decimal place.
Kindergarten students were participants in a study investigating fine motor skills of 37 children. The children had their fine motor skills measured before the study (a combination of hand use, eye-hand coordination, and manual dexterity) and again after undergoing 7 months of occupational therapy. With the instrument used, high scores indicated stronger fine motor skills. Summary statistics are given below: Difference n Sample Diff Std. Err. Min Max d = Pre - Post 37 -7.8109 2.0715 -36 9 Determine what positive and negative differences mean regarding a student's fine motor skills. Pay attention to the order of subtraction in the output.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
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.
