2.2.25 According to a Pew Research Center report from 2012, the average commute time to work in California is 27.5 minutes. To investigate whether a different average is true for the small city that she lives in, a California high school student surveys 45 people she knows-her teachers, her parents and their friends and co-workers-and finds the average commute time for this sample to be 24.33 minutes, with a standard deviation of 9.53 minutes.

Please see below. I only have one attempt at this. I really need help with this. Does duct tape work better than cryotherapy for removing warts in children and young adults? Of 26 patients treated with duct tape, 22 showed complete wart remission. In comparison, 15 of the 25 patients treated with cryotherapy achieved complete wart remission. Which test is most appropriate for this scenario? A. 2-sample test for means B. 1-sample z-test for proportions C. 2-sample test for proportions D. matched-pairs E. 1-sample t-test for means
Please see below. Only given one attempt at this. People who sustain a concussion or a traumatic brain injury (TBI) are likely to experience sleep problems. Do these problems persist over time? Researchers recruited a sample of 31 patients who had their first TBI 18 months earlier and a control group of 42 otherwise similar individuals without prior TBIs. They compared sleep duration per 24 hours for the 2 groups. Which test is most appropriate for this scenario? A 2-sample test for means B 1-sample z-test for proportions C 2-sample test for proportions D matched-pairs E 1-sample t-test for means
frisi wants to check the support of political parties in the Reykjavík area and decided to stand at the entrance of Kringlan one weekend and ask people what they are going to vote for. It was Kringlukast and a lot of good offers so many made their way there this weekend. Iris received a total of 834 answers to the question, what are you going to vote for in the upcoming election? "What is the main statistical problem with Iris' survey? 1. It is not corrected for placebo effect. 2. There is a risk of research bias in the survey. 3. There is a risk of sampling in the survey. 4. The number of participants is small and therefore the hypothesis tests that will be performed will have little strength.

2a. (Data calories.txt) For this problem, focus on the random sample obtained using only treatment 1. What is the average number of calories consumed for children in this group? Use 2 decimals Hint: Don't forget to only use the subset of children that participated in meal prep aration. 2b. (Data calories.txt only using treatment 1 sample) Based on these data, obtain the standard error for the average of calories consumed by children participating in meal preparation. Enter the value using two decimals. Hint 2: The R command length() may be useful to find the appropriate sample size. 2c. (Data calories.txt only using treatment 1 sample) A researcher would like to show that children participating in meal preparation (treatment 1) consume more than 400 calories, on average. Use the results obtained in the previous two questions and obtained the test statistic. Enter it here using two decimals. 2d.
