MY NOTES ASK YOUR TEACHER PRACTICE ANOTHI A certain magazine stated that the mean time for a Ford Mustang to go from 0 to 60 miles per hour is 4.9 seconds. (a) If you want to set up a statistical test to challenge the claim of 4.9 seconds, what would you use for the null hypothesis? Ou 4.9 O u + 4.9 (b) The town of Leadville, Colorado, has an elevation over 10,000 feet. Suppose you wanted to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer in Leadville (because of less oxygen). What would you use for the alternate hypothesis? OH > 4.9 OH $ 4.9 OH = 4.9 OH 4.9last: dep-30 133533 inDOX - Kolege246... G Google Ad Grants e... Taxpayer Bill of Rig... Screenshot of the F.. Partner Entry | Roge... 5 Army NG G1 Portal 5. [-/1 Points] DETAILS BBBASICSTAT8 9. 1.004. MY NOTES If we reject the null hypothesis, does this mean that we have proved it to be false beyond all doubt? Explain your answer. O No, the test was conducted with a risk of a type I error. O Yes, if we reject the null that suggests that it is false beyond all doubt. O No, the test was conducted with a risk of a type II error. O Yes, the test was conducted with a risk of a type I error.(d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level a? At the a - 0.05 level, we reject the null hypothesis and conclude the data are statistically significant. At the a = 0.05 level, we reject the null hypothesis and conclude the data are not statistically significant. At the a = 0.05 level, we fail to reject the null hypothesis and conclude the data are statistically significant. At the a = 0.05 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (e) Interpret your conclusion in the context of the application. There is sufficient evidence at the 0.05 level to conclude that the drug has changed the mean pH level of the blood. There is insufficient evidence at the 0.05 level to conclude that the drug has changed the mean ph level of the blood.osoft Word - Bio 101 Online X M Inbox (5) - kolege246@gmail.cor x webassign.net/web/Student/Assignment-Responses/last?dep-30133533 Q 1 X ge246...

For healthy adults, the red blood cell volume mean is about u = 28 ml/kg. + Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows. 33 27 39 37 30 37 27 Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and o = 4.75. Do the data indicate that Roger's red blood cell volume is different (either way) from u = 28 ml/kg? Use a 0.01 level of significance. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? O Ho: H = 28 ml/kg; H, : u # 28 ml/kg; two-tailed O H: M = 28 ml/kg; H, : u > 28 ml/kg; right-tailed O Ho: H = 28 ml/kg; H, : u 7.4 O Ho : H = 7.4; H1 : H 7.4 ; H, : 1 = 7.4 OH : M # 7.4 ; H , : 1 = 7.43 (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level a? At the a = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant. At the a = 0.01 level, we reject the null hypothesis and conclude the data are not statistically significant. O At the a = 0.01 level, we fail to reject the null hypothesis and conclude the data are statistically significant. At the a = 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. (e) State your conclusion in the context of the application. There is sufficient evidence at the 0.01 level to conclude that Roger's average red cell volume differs from the average for healthy adults.

O The standard normal, since the sample size is large and o is known. O The Student's t, since the sample size is large and o is known. O The Student's t, since the sample size is large and o is unknown. The standard normal, since the sample size is large and o is unknown. What is the value of the sample test statistic?
