[2] TYPES OF STUDIES [Part 1]: Forty 60-65 year old males have agreed to participate in an eight-week study of t effectiveness of four weight/cardio training approaches on overall retention of muscle mass. At the start of the investigation the researcher calculates the muscle circumference in the upper thigh and the upper arm and calculate a body mass index (BMI) for each participant. Each participant is then randomly assigned to one of the four weight/cardio training approaches. The muscle circumference and BMI measurements are taken again at the end the study. This is an example of alan: A. Experiment B. Observational study C. Simulationn

Exercise on ANOVA 1. A dietition wanted to test three different diets to find out if the mean weight loss for each of these diets is the same. She randomly selected 21 overweight person, randomly divided them into three groups, and put each group on one of the three diets. The following table records the weights (In kg) loss by these persons after being on these diets for two months. Diet 1 Diet 2 Diet 3 15 11 9 8 16 17 17 9 11 7 16 8 26 24 15 12 20 6 8 19 14 a) We are to test if the mean weight lost by all persons on each of the three diets is the same. Write the null and alternative hypotheses. b) Show the rejection and nonrejection regions on the F distribution curve for a=0.025. c) Calculate SSB, SSW, and SST. d) What are the degrees of freedom for the numerator and denominator? e) Calculate the between-samples and within-samples variances. f) What is the critical value of F for α=0.025. g) What is the calculated value of the test statistic F? h) Write the ANOVA table for this…

Hypnosis and Pain. In the paper “An Analysis of Factors That Contribute to the Efficacy of Hypnotic Analgesia” (Journal of Abnormal Psychology, Vol. 96, No. 1, pp. 46–51), D. Price and J. Barber examined the effects of hypnosis on pain. They measured response to pain using a visual analogue scale (VAS), in centimeters, where higher VAS indicates greater pain. VAS sensory ratings were made before and after hypnosis on each of 16 subjects. A hypothesis test is to be performed to decide whether, on average, hypnosis reduces pain. a. identify the variable. b. identify the two populations. c. identify the pairs. d. identify the paired-difference variable. e. determine the null and alternative hypotheses. f. classify the hypothesis test as two tailed, left tailed, or right tailed.
Sample data were collected in a study of calcium supplements and their effects on blood pressure. A placebo group and a calcium group began the study with measures of blood pressures for each group.

Study Purpose: The purpose of this randomized controlled trial was to determine the impact of an app-based digital care program to treat chronic lower back pain compared to usual treatment. Post intervention pain scores were measured using Korff pain measurement scale that ranges from 0 (minimum) to 100 (maximum). The results for this study are summarized in the table below. Table: Mean Pain Reports Change in mean Change in mean Mean difference P- value pain score pain score (95% CI) Intervention group Control group (n=113) (n=64) Korff pain score -25.3 1.6 -26.9 (-33.8, -20) <0.001 Answer the following questions using data from the table above: 1. Is the result for the primary outcome (pain) statistically significant? Answer: YES or NO 2. Explain your answer
Calcium is the most abundant mineral in the human body and has several important functions. Most of the body calcium is stored in the bones and teeth, where it functions to support their structure. Recommendations for calcium are provided in Dietary Reference Intakes, developed by the Institute of Medicine of the National Academy of Sciences. The recommended adequate intake (RAI) for calcium for adults (ages 19-50) is 1000 mg per day. A random sample of 18 adults with incomes below the poverty level gave the following calcium intakes:886 633 943 847 934 8411193 820 774 834 1050 10581192 975 1313 872 1079 809Assume the population standard deviation for daily calcium intake for adults with incomes below the poverty level is 188mg.At the 0.05 level of significance, does the data provided above provide evidence to suggest that the mean calcium intake of all adults with incomes below the poverty level is less than the RAI pf 1000mg per day?
