- Adult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score of a man 75.6 inches tall. (to 2 decimal places) Submit QuestionConsider a value to be significantly low if its z score less than or equal to - 2 or consider a value to be significantly high if its z score is greater than or equal to 2. Atest is used to assess readiness for college. In a recent year, the mean test score was 21.3 and the standard deviation was 4.7. Identify the test scores that are significantly low or significantly high. What test scores are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice. O A. Test scores that are greater than (Round to one decimal place as needed.) O B. Test scores that are between and (Round to one decimal place as needed. Use ascending order.) OC Test scores that are less than (Round to one decimal place as needed.)iger 2. Hypothesis: College students sleep less than the recommended 8 hours. Data: Sample mean (X) = 7.25, sample standard deviation (Sx) = 2.1, N = 25.
- Test the claim that the standard deviation of the ages of Phychologist in California us 7.3 at 0.01 level of significance. a random sample of 15 psychologist had a standard deviation of 6.9. Find the test valueDaily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 23.4. The population standard deviation is 4.1 miles. At a = 0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical value method with tables. Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. H: u = 24 not claim Η: μ 24 claim The hypothesis test is a one-tailed test. Part: 1/5 Part 2 of 5 Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 22.5. The population standard deviation is 4.1 miles. At a = 0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the P-value method with a graphing calculator. Part: 0 / 4 Part 1 of 4 (a) State the hypotheses and identify the claim. H,: (Choose one) ▼ OHeight and age: Are older men shorter than younger men? According to a national report, the mean height for U.S. men is 69.4 inches. In a sample of 300 men between the ages of 60 and 69, the mean height was * = 68.7 inches. Public health officials want to determine whether the mean height u for older men is less than the mean height of all adult men. Assume the population standard deviation to be o =3.42. Use the a = 0.05 level of significance and the P-value method with the TI-84 calculator. Answer the following.Consider a set of data in which the sample mean is 27 and the sample standard deviation is 6.2. Calculate the z-score given that x = 28.5. Round your answer to two decimal places. AnN=80 p=.6 mean? variance? standard deviation?Daily Driving The average number of miles a person drives per day is 24.
