- Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.8 parts/ million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 9 samples is 4.3 PPM with a standard deviation of 0.6. Assume the population is normally distributed. A level of significance of 0.05 will be used. find the value of the test to statistic. round your answer to 3 decimal places.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.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 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.

I solved everything else on my own.How much money on average does a fan of professional football spend on food at a single football game? This question was posed to 71 randomly selected football fans. The sample results provided a sample mean and standard deviation of 15.15 euro and 2.6 euro, respectively. Estimate the value of the population mean, μ, the mean amount of money football fans spend on food at a single game. Fill in the blanks in the following: • An estimate of the population mean is 15.15 • The standard error is • The distribution is normal (examples: normal/t12/chisquare4/F5,6). For a 90% confidence interval the distributional cut-off is It is quite likely that the true mean amount of money football fans spend on food at a single game is between with 90% confidence. andz Scores LeBron James, one of the most successful basketball players of all time, has a height of 6 feet 8 inches, or 203 cm. Based on statistics from Data Set 1 “Body Data” in Appendix B, his height converts to the z score of 4.07.
