Researchers want to test a new hand exercise plan for arthritis patients to see if they have improvedflexibility. They recruited 110 patients with arthritis in their hands and randomly assigned them to one oftwo treatment groups: group i took their regular medicine and did the new hand exercises; and group 2only took medicine. After one month, 42 of the 55 in group 1 improved in their flexibility, and 37 of the55 in group 2 improved their flexibility.Based on the 95% confidence interval (-0.076, 0.258), is there convincing evidence of a difference inthe proportion of patients like these who would show improvement in flexibility if they did the new handexercises along with taking the medicine versus just taking the medicine?v to believe thereva difference in the proportion of patients like these who would show improvement in flexibilityif they did the new hand exercises along with taking the medicine versus just taking the medicine.Becausev contained in the interval, there is

In a random sample of 392 people that were tested for the Norcovirus, it was found that 314 did not have the virus. A 97% confidence interval was constructed to estimate the proportion of the population that does not have the Norcovirus. This confidence interval came out to be (0.76,0.84).

It is estimated that in the general population about 9 out of every 1000 or 0.009 children are diagnosed with autism. on study included 92 six month old babies who had a sibling with autism. twenty-eight of these babies were later diagnosed with autism. we will systematically construct a 99% confidence interval for the proportion of siblings of autistic children likely to have autism. What is the population being studied? What population parameter are we seeking to estimate? Describe this population parameter in words.

A repeated measures study is done to measure the change in IQ test scores taken on Monday versus those taken on Friday. There were n=9 participants in the study. The mean difference was MD =-5 points and the standard error for the mean difference was SMD=0.51. Construct a 95% confidence interval to estimate the size of the population mean difference.
A researcher surveys a group of college students to determine the negative life events that they experienced in the past 5 years and their current feeling of well-being. For N = 18 participants with 2 or fewer negative experiences, the average well-being score was X = 42 with SS = 398. For the N = 16 participants with 5 to 10 negative experiences the average score is X = 48.6 with SS = 370. Construct a 95% confidence interval for the difference between the population means for the two groups.
A study is conducted by a physical therapist to determine whether there is a difference in the proportion of men and women in the U.S. that participate in regular sustained physical activity. It is found that 22% of menout of 550 and 19.5% of women out of 450 participated in regular sustained physical activity. Construct a 90% confidence interval for the difference in proportions of men and women that participate in regular sustained and state your conclusion.
A sample of 1200 females and 1000 males found that 78.3% of females and 35.1% males supported increased funding of arts. Construct a 90% confidence interval around the difference in proportions.
An article claims that babies spend twice as much time in REM (rapid eye movement) sleep than adults. This implies that babies have an average of 6 hours of REM sleep per night. A doctor would like to test the hypotheses = 6 versus ≠ 6 where = the true mean amount of REM sleep per night for babies. A 95% confidence interval for the true mean amount of REM sleep per night for babies is (5.45, 6.25) hours. Based on the confidence interval, what conclusion would you make for a test of these hypotheses? The 95% confidence interval include as a plausible value, so we H0. We convincing evidence that the true mean amount of REM sleep per night for babies 6 hours.
A random sample of high school seniors were asked whether they were applying for college. The resulting confidence interval for the proportion of students applying for college is (0.65,0.69). What is the margin of error?
Many teens have posted profiles on sites such as Facebook. A sample survey asked random samples of teens with online profile if they included false information in their profiles. Of 170 younger teens (ages 12 to 17) polled, 117 said "Yes." Of 317 older teens (ages 15 to 17) polled, 152 said "Yes." A 95% confidence interval for py - Po = the true difference in the proportion of younger teens and older teens who include false information in their profile is 0.12 to 0.297. Does the confidence interval give convincing evidence of a difference in the true proportions of younger and older teens who include false information in their profiles? Explain your answer. O Even though this confidence interval does not include 0, this might not occur again in different samples. There is not enough evidence to make a conclusion regarding the true difference in the proportion of younger teens and older teens who include false information on their profiles. No. We are 95% confident that the interval…
