Q1 Researchers selected 885 patients at random among those who take a certain widely-used prescription drug daily. In aclinical trial, 18 out of the 885 patients complained of flulike symptoms. Suppose that it is known that 1.5% of patientstaking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.5% ofthis drug's users experience flulike symptoms as a side effect at the x = 0.05 level of significance?Because npo (1 - Po) =10, the sample size isselected at random, all of the requirements for testing the hypothesissample(Round to one decimal place as needed.)5% of the population size, and the patients in the▼satisfied.

What is an experiment?
In a clinical trial, 17 out of 900 patients taking a prescription drug complaint of flu like symptoms. Suppose that it is known that 1.3% of the patients taking competing drugs complain of flu like symptoms. Is there sufficient evidence to conclude that more than 1.3% of the drugs user experience food like symptoms as a side effect at the 0.01 level of significance? what are the normal and alternative hypothesis?
A cross-sectional study of 1,900 participants looked at the association between Normal Course Load (12-15 credit hours (CH)) and Anxiety among upperclassmen college students (Junior & Senior). The study included 1,000 students with a High Course Load. This study also discovered a total of 850 cases of Anxiety. Of those with a Normal course load 12% were diagnosed with anxiety like symptoms by a school psychologist.

In a study conducted by the U.S. Department of Health and Human Services, a sample of 546 boys aged 6–11 was weighed, and it was determined that 87 of them were overweight. A sample of 508 girls aged 6–11 was also weighed, and 74 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight? Please show calcul
Results from the National Health and Nutrition Examination Survey (NHANES) conducted thirty years ago revealed that out of 378 randomly selected adults in the United States 57 were considered to be obese. In this year’s National Health and Nutrition Examination Survey, out of 426randomly selected adults in the United States 135 were considered to be obese. Based on these results, can one conclude, at the 0.01 level of significance, that the percentage of adults in the United States that are obese is considerably higher now than it was thirty years ago?
A clinical trial is run to assess the effectiveness of a new drug in lowering blood pressure. Patients are randomized to receive the new drug or placebo and systolic blood pressure is measured after 12 weeks on the assigned treatment. Is the mean systolic blood pressure for patients in the new drug group significantly lower than the mean systolic blood pressure for patients in the placebo group after the 12 week treatment?

A researcher was interested in how the effects of stress were different in people with our without military training. A equal number of participants were recruited that either had no military experience or had completed military experience. All participants were asked to give a speech without preparation while being judged by a panel of experts. Their heart rates were monitored during the speech and an average heart rate was calcuated for each participant. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA
of 15 > Attention-deficit/hyperactivity disorder (ADHD) is a brain disorder that results in recurring patterns of inattention and hyperactivity and which may interfere with functioning or development. A recent study compared the prevalence and rate of medication for ADHD in American children by gender and state (Visser et al., 2013). The proportion of girls and boys diagnosed with ADHD varied by age. The sample size of children included in the study varied by state, as did the number of boys and girls diagnosed with ADHD. Match each numerical range to the description of the data that it is most likely to represent. the range in the ages of individuals included in the study the range in the percent of children in each state that are taking medication for ADHD the range in the proportion of all girls who have been diagnosed with ADHD and who are medicated, by age the range in the number of interviews conducted to obtain the data, per state the range in the ratio of ADHD prevalence in…
A clinical trial is run among 40 HIV patients in order to assess the effectiveness of a new anti-retroviral therapy. Patients are randomized. One group received the standard anti-retroviral therapy (usual care) while the other group received the new anti-retroviral therapy. They are monitored for three months. The primary variable is the viral load which represents the number of HIV copies per milliliter of blood. The most appropriate statistical test to determine the significant difference in viral load in patients receiving the standard versus the new anti-retroviral therapy is Mann- Whitney U Test. a.True b.False
