A greenhouse wants to test the effectiveness of alternative fertilizers on plant growth. One sample of 400 is treated with brand A & another 400 was treated with brand B. After 2 weeks results showed that 150 bloom from brand A and 130 bloom from brand B. What can it conclude at 0.05 level of significance that the 2 brands are not equally effective?. What is the computed value and decision?

The athletic director at a large university compared the proportions of freshmen (1st year students) and seniors (4th year students) who exercise regularly. She analyzed the data and found the Z-statistic for the difference between the population proportions to be 2.43 with a P-value of 0.015. The level of significance was set at 0.05. State the conclusion she can draw about the difference between the two population proportions.
A therapist named Dr. Brown specializes in adolescent anxiety and has been collecting information about the frequency of all clients' anxiety symptoms (a higher number means more frequent symptoms) and comparing them using z-scores. Alex has a z-score of 1.6. What can we infer about Alex's frequency of anxiety symptoms?
A pharmaceutical company wants to test whether their the incidence of side effects (i.e. adverse events) differs between the treatment and placebo groups at the a = 0.05. Let pı = the proportion of subjects in the treatment groups who experienced at least one adverse event and let p2 = the proportion of subjects in the placebo group who experience at least one adverse event. 8 out of 30 people in the treatment group experienced at least one adverse event and 5 out of 30 people in the placebo group experienced at least one adverse event. (a) Set up the null and alternative hypothesis (using mathematical notation/numbers AND interpret them in context of the problem) (b) Calculate the test statistic (c) Calculate the critical value (d) Draw a picture of the distribution of the test statistic under Ho. Label and provide values for the critical value and the test statistic, and shade the critical region. (e) Make and justify a statistical decision at the a = 0.05 level and state your…
A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y) Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 125 patients from the city and estimates the following regression function: Y= 15.50 + 0..90B+1.15A. (0.55) (0 40) The test statistic of the study the student wants to conduct (Ho: B, = 0 vs. H, B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will ▼ the null hypothesis. Keeping BMIl constant, she now wants to test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure. So, the test statistic associated with the one-sided test the…
A pharmaceutical company is testing a new drug for reducing cholesterol levels. to approve the drug for the next round of testing, they need to show that this drug reduces mean total cholesterol level by at least 50 mg/dL. They initially plan a study that involves 50 subjects and a significance level of 0.05, but they discover that the power of the test against this effect size is only 0.24. what are two ways they can increase teh power of the test without changing effect size?
A researcher would like to examine how the chemical tryptophan, contained in foods such as turkey, can affect mental alert ness. A sample of n = 9 college students is obtained, and each student's performance on a familiar video game is measured before and after eating a traditional Thanksgiving dinner including roast turkey. The average score dropped by MD = 14 points after the meal with SS = 1152 for the difference scores. 1. Is there a significant difference in performance before eating versus after eating? Use a two-tailed test with a = Show all calculations. a. State the research hypotheses b. Identify the critical value c. Calculate the test statistic d. Evaluate the null hypothesis
A certain drug can be used to reduce the acid produced by the body and heal damage to the esophagus due to acid reflux. The manufacturer of the drug claims that more than 92% of patients taking the drug are healed within 8 weeks. In clinical trials, 210 of 226 patients suffering from acid reflux disease were healed after 8 weeks. Test the manufacturers claim at the a=0.05 level of significance
An experiment was conducted to evaluate the effect of decreases in frontalis muscle tension on headaches. The number of headaches experienced in a 2-week baseline period was recorded in 9 subjects who had been experiencing tension headaches. Then the subjects were trained to lower frontalis muscle tension using biofeedback, after which the number of headaches in another 2-week period was again recorded. The data are shown below. No. of Headaches Subject No Baseline After Training 1 17 3 2 13 7 3 6 2 4 5 3 5 5 6 6 10 2 7 8 1 8 6 0 9 7 2 Assume the t-test cannot be used because of an extreme violation of its normality assumption. Use the Wilcoxon signed ranks test to analyze the data. What do you conclude, using α = 0.05 2tail?
Medical tests were conducted to learn about drug-resistant tuberculosis. Of 142 cases tested in New Jersey, nine were found to be drug resistant. Of the 268 cases tested in Texas, 20 were found to be drug-resistant. Does the data suggest a lower presence of drug-resistant tuberculosis in New Jersey? Use a 0.025 level of significance to obtain the critical value(s) and make your conclusion.
A researcher is investigating the effect of acupuncture treatment for chronic back pain. A sample of n = 4 participants is obtained from a pain clinic. Each individual ranks the current level of pain and then begins a 8-week treatment. At the end of the program, the pain level is rated again. For this sample, pain level decreased by an average MD = -4.5 points with SS = 27. Can you conclude that acupuncture treatment significantly reduces back pain? Use α = .05.
Here's a new idea for treating advanced melanoma, the most serious kind of skin cancer: genetically engineer white blood cells to better recognize and destroy cancer cells, then infuse these cells into patients. The subjects in a small initial study were 11 patients whose melanoma had not responded to existing treatments One outcome of this experiment is measured by a test for the presence of cells that trigger an immune response in the body and so may help fight cancer. Here are data for the 11 subjects: counts of active cells per 100,000 cells before and after infusion of the modified cells. The difference (after minus before) is the response variable.
