- based on these findings, at least two hypotheses that you are testing in this project. Your hypotheses can have the same dependent variable, but they should have different independent variables. (Happiness and physical health"A researcher investigated the short-term effect of including classical music on the standard relaxation therapy used in the treatment of smoking. The researcher investigated whether slow classical music when included with relaxation therapy has any significant effect on the behavior of smoking cigarettes. The slow classical music used with the therapy is the “Piano Concerto in A minor” by Edvard Grieg. A piano concerto is a type of concerto, a solo composition in the classical music genre, which is composed for a piano player and is typically accompanied by an orchestra or other large ensemble. Participants who smoked at least one pack of cigarettes a day (20 cigarettes in a pack) were randomly assigned to one of two groups. The participants in condition one received relaxation therapy that included classical music. The second condition consisted of participants who served as a control group and were given the same relaxation therapy but did not include the slow classical music. The…Could you please highlight the correct answer. and explain it

However, certain side effects have been reported with pump therapy. Table 2 provides data on the occurrence of diabetic ketoacidosis (DKA) in patients before and after start of pump therapy.

What is the appropriate procedure to test whether the rate of DKA is different before and after start of the pump therapy? 11. Perform the significance test in Problem 10, and report a p-value.
- You wish to test whether a particular drug manages to bring body temperature down. So, you conduct a pilot study where 47 people receive the drug, and 45 people receive a placebo. The body temperatures of patients from the treatment group are group 1 (variable X1); those from the placebo group are group 2 (variable X2). What is the research hypothesis? mu1 > mu2 mu1 ≠ mu2 mu1 < mu2 mu1 = mu2Answer question c onlyQuestion 19 Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. • Lucille's class had an average grade of 77 and the standard deviation was 4. Lucille earned 84.2 on the exam. Rocio's class had an average grade of 85 and the standard deviation was 3. Rocio earned 85.6 on the exam. Cristina's class had an average grade of 85 and the standard deviation was 5. Cristina earned 91.5 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam. Use the Cumulative Z-Score Table to answer the following questions. Write your answers as a percent with two decimal places. Hint • Lucille's score places her above % of her class. % of her class. Rocio's score places her above % of her class. • Cristina's score places her above Which person has the highest…
