7.16 Using an app or the Web on a smartphone. The Nielsen Company reports that U.S. residents aged 18 to 34 years spend an average of 2.83 hours per day using an app or the Web on a smartphones You wonder if this it true for students at your large university because you rarely see students not using their smartphones. You collect an SRS of n = 75 students and obtain 2 = 3.17 hours with s =1.36 hours. (a) Report the 95% confidence interval for u, the average number of hours per month that students at your university use the Internet on a computer. (b) Use this interval to test whether the average time for students at your university is different from the average, reported by Nielsen. Use the 5% significance level. Summarize your results.
A researcher in nursing wanted to know if the recovery of patients was quicker when some received additional in-home care whereas others received the standard amount. Would you perform a t-test of independent means or a t-test of dependent means?
Could also you please show how to find Critial Values, Test Statisitc T, and the P value using a Calculator (TI 84) and whether it reject or fail to reject based on the evidence.
A human factors psychologist is interested in how alcohol impacts driving performance. A sample of participants was randomly assigned into one of three different conditions of alcohol blood levels (abl). The participants then operate a driving simulator and each participant was measured on how much time (in seconds) they spent on a target when steering. The more time they spend on a target, the better their driving skills. What can the psychologist conclude with an α of 0.01? abl 1 abl 2 abl 3 221192171247234281238171 180146178134200170208156 180132172137154154176178 A) Obtain/compute the appropriate values to make a decision about H0.critical value = ; test statistic = Decision: B) Compute the corresponding effect size(s) and indicate magnitude(s).η2 = Magnitude= C) Conduct Tukey's Post Hoc Test for the following comparisons:2 vs. 3: difference = 1 vs. 3: difference = Conduct Scheffe's Post Hoc Test for the following comparisons:1 vs. 3: test statistic = 1…
The manager of the city pool has scheduled extra lifeguards to be on staff for Saturdays. However, he suspects that Fridays may be more popular than the other weekdays as well. If so, he will hire extra lifeguards for Fridays, too. In order to test his theory that the daily number of swimmers varies on weekdays, he records the number of swimmers each day for the first week of summer. Test the manager’s theory at the 0.01 level of significance. Swimmers at the City Pool Monday Tuesday Wednesday Thursday Friday Number 64 46 41 56 70 Copy Data Step 2 of 4 : Calculate the expected value for the number of swimmers on Tuesday. Enter your answer as a fraction or a decimal rounded to three decimal places.
Twenty years ago, 56% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 308 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the α = 0.05 level of significance. Because npo (1-Po) = 197.1 > 10, the sample size is (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: P 0.56 versus H₁: р (Type integers or decimals. Do not round.) Find the test statistic. # 0.56 Zo -9.97 (Round to two decimal places as needed.) = Find the P-value. P-value = (Round to three decimal places as needed.) less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied.
Foofy obtained a significant Fobt from an experiment with five levels. She therefore concludes that changing every condition of the independent variable results in a significant change in the dependent variable. (a) Is she correct? Why or why not? (b) What must she now do?
If we use a cutoff of 0.05, is it unusual for someone to have a great deal of confidence in educational institutions?
Research has shown that losing even one night’s sleep can have a significant effect on performance ofcomplex tasks such as problem solving (Linde &Bergstroem, 1992). To demonstrate this phenomenon,a sample of n=25 college students was given aproblem-solving task at noon on one day and again atnoon on the following day. The students were notpermitted any sleep between the two tests. For eachstudent, the difference between the first and secondscore was recorded. For this sample, the studentsaveraged MD=4.7 points better on the first test with avariance of s2=64 for the difference scores. a.Do the data indicate a significant change in problem-solving ability? Use a two-tailed test with a= .05. b.Compute an estimated Cohen’s dto measure thesize of the effect
