The null hypothesis for a research study states that u = 80. If a researcher obtains a sample of n = 25
with M = 89 and SS = 108, then Cohen's d =
O 1.5, which demonstrates a large effect
O 4.25, which demonstrates a large effect
O 0.56, which demonstrates a medium effect
O 2.12, which demonstrates a small effect

Suppose an experiment finds that people taking a new herbal remedy get fewer colds than people taking a placebo. The results are statistically significant at the 0.01 level. Has the experiment proven that the herbal remedy works?
At the Olympic level of competition, even the smallest factors can make the difference between winning and losing. For example, Pelton (1983) has shown that Olympic marksmen shoot much better if they fire between heartbeats, rather than squeezing the trigger during a heartbeat. The small vibration caused by a heartbeat seems to be sufficient to affect the marks-man’s aim. The following hypothetical data demonstrate this phenomenon. A sample of n = 6 Olympic marksmen fires a series of rounds while a researcher records heartbeats. For each marksman, a score is recorded for shots fired during heartbeats and for shots fired between heartbeats. Do the data indicate a significant difference? Test with α = .05.

Q. 3 A researcher calculated the negative predictive value of a test for carriers of X-linked ornithine transcarbamylase deficiency (OTCD - a disorder of the urea cycle). A test known as the "allopurinol test" is often used as a screening device of potential carriers whose relatives are OTCD patients. Sensitivity and specificity of the allopurinol test is estimated the as 0.927 and 0.997 respectively Also the prevalence is estimated in the population of individuals with OTCD as (1/32000). Use this information and Bayes theorem to calculate the predictive value negative of the allopurinol screening test.

Refer to Exercise 8.S.1. Compare the before and after populations using a t test at α = 0.05. Use a nondirectional alternative.
A study published by Babcock and Marks (2010) showed that the average full-time U.S. college student studied for μ = 14 hours per week (SD = 4.8 hours per week) in 2005. We want to know if this average has changed in the past 15 years. In other words, we are going to do a study in which we try to determine whether there has been an impact of the passage of time on the amount of time college students spend studying. We selected a sample of n = 64 of today’s college students and find that they spent an average of M = 12.5 hours per week studying. Does this sample indicate a significant change in the number of hours spent studying? Use a two-tailed test (this means non-directional hypothesis) with α = .05.
It has been found that 27.6% of men (Group 1) 20 years and older suffer from hypertension (high blood pressure) and 33.1% of women (Group 2) are hypertensive. A random sample of 169 of each gender was selected from recent hospital records, and the following results were obtained. Can you conclude that a higher percentage of women have high blood pressure? Use α=0.05. Men: 39 patients had high blood pressure Women: 54 patients had high blood pressure Required: Test Value Only the final answer should be rounded-off to TWO decimal places. Add your answer
Do types of crimes reported on television newscasts differ by the age of the criminals? A researcher uses her dvr to record the local television news for a 2-week period of time. She records the types of crimes and notes the age of the offender. Conduct a chi-square test (alpha = .05) of the null hypothesis that televised offense type does not vary by age group of offender. Offense type Young middle age older violent 27 10 3 property 14 12 11 sex 7 9 5 Report the obtained chi-square, df, and critical chi-square. Report your findings based on the null hypothesis.

Q3. Kaimura et al. (2000) investigated the effects of procyanidin B-2 tonic on human hair growth after sequential use for 6 months. In one part of the study, the total hair increase (total hairs at month 6 – total hairs at month 0) in the designated scalp area was measured for a sample of 15 men treated with a placebo control and a sample of 25 men treated with a procyanidin B-2 (PB2). The data is contained in the file A2Q3.csv. (This data is simulated based on information in the paper. You must use the data in the file to carry out the analysis). Is there evidence that the total hair increase of the subjects in the procyanidin B-2 group was greater the those in the placebo control group, at the 5% level of significance? State an appropriate null and alternative hypothesis in words and symbols.
Recent results suggest that children with ADHD tend to watch more TV than children who are not diagnosed with the disorder. To examine this relationship, a researcher obtains a random sample of n = 36 children, 8 to 12 years old, who have been diagnosed with ADHD. Each child is asked to keep a journal recording how much time each day is spent watching TV. The average daily time for the sample is M = 4.9 hours. It is known that the average time for the general population of 8 to 12-year-old children is = 4.1 hours with = 1.8. (Hint: Be sure to use the correct test statistic). Are the data sufficient to conclude that children with ADHD watch significantly more TV than children without the disorder? Use a two-tailed test with = .05. (Be sure to give your conclusion, too) If the researcher had used a sample of n = 9 children and obtained the same sample mean, would the results be sufficient to reject H0? (Be sure to give your conclusion, too) Compute Cohen's d for this study. What is…
