- A diet center wanted to test three different methods for losing weight to determine if the average weight loss (reported in pounds/week) for each method is the same. The results for the three methods are tabulated below. Given that there is a significant difference between the three methods, use the Tukey test to determine if there is a significant difference between each pair of methods. Let a=0.05. (picture attached)A survey of 90 recently delivered women on the rolls of a county welfare department revealed that 27 had a history of intrapartum or postpartum infection. Can we conclude that the population proportion with a history of intrapartum or postpartum infection is significantly less than or equal to 0.25? Let alpha = 0.05.A sample of n= 64 scores is selected from a population with u =60 and o= 10. If the sample mean is M = 57, what is the z-score for this sample mean? Oz=-2.40 Oz=+1.00 Oz=-2.00 Oz= +4,00
- he personality trait of "Conscientiousness" (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. What is the correct result based on the data?55% of students entering four-year colleges receive a degree within six years. Is this percent smaller than for students who play intramural sports? 93 of the 203 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of αα = 0.10? The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.)Sixty teachers were interviewed regarding their opinion on the issue of increasing the number of years of basic education from 10 to 12years. Do these teachers differ significantly in their opinion on this issue? Test the claim at α=0.05. Agree – 32, Disagree – 10, Undecided – 18 What is the tabulated value and the statistical value?
- The sample data for a t-test of Ho:u=15 and H2: µ >15 are sample mean=16.2, s=3.1 and n=18. Use a = 0.05 to draw your conclusion. (Ott, 1993)In a test of H0:p=0.4 against Ha:p≠0.4, a sample of size 100 produces z=1.28 for the value of the test statistic. Thus the p-value of the test is approximately equal to?For Z-test used to analyze data on tablet weight in a batch with Ho: u = 300 mg and at a = 0.05. If a sample was taken from the batch and Z-score of the mean tablet weight of the sample was correctly calculated as 1.9. P-value is which suggest that, O 0.047, The mean tablet of the batch is not significantly different from 300 O 0.0574, The mean tablet of the batch is significantly different from 300 O 0.0287, The mean tablet of the batch is not significantly different from 300 O 0.047, The mean tablet of the batch is significantly different from 300 O0.9713, The mean tablet of the batch is significantly different from 300 0.9713, The mean tablet of the batch is not significantly different from 300 0.0287, The mean tablet of the batch is significantly different from 300 0.0574, The mean tablet of the batch is not significantly different from 300 Next pc
- To examine the relationship between alcohol consumption and birth weight, a researcher selects a sample of n = 20 pregnant rats and mixes alcohol with their food for 2 weeks before the pups are born. One newborn pup is randomly selected from each subject’s litter and the average with weight for the n = 20 pups is recorded. It is known that the average birth weight for regular rats (without exposure to alcohol) is μ = 5.6 grams. What type of test would you use to test the hypothesis that alcohol consumption during pregnancy reduces birth weights? Would you use a one-tailed or two-tailed test? What would be an appropriate measure of effect size to report?A survey of 90 recently delivered women on the rolls of a county welfare department revealed that 27 had a history of intrapartum or postpartum infection. What is the critical value of z if we need to conclude that the population proportion with a history of intrapartum or postpartum infection is less than 0.25.A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at a = 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects. The sample proportion of women who suffer effects from the pill is: a. 0.1144 Ob. 1.444 OC. 0.1000 d. 0.0144 O e. 0.0743
