A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, µ, of the population from which the sample was drawn. Use the critical-value approach. x= 24.4, s = 9.2, n= 25, Ho: H = 26, Hgi µ < 26, a = 0.05 O A. Test statistic: t= - 4.35. Critical value: t= - 1.708. Reject Ho. There is sufficient evidence to conclude that the mean is less than 26. O B. Test statistic: t= - 4.35. Critical value: t= - 1.711. Reject Ho. There is sufficient evidence to conclude that the mean is less than 26. OC. Test statistic: t= - 0.87. Critical value: t= - 1.708. Do not reject Ho. There is not sufficient evidence to conclude that the mean is less than 26. O D. Test statistic: t= - 0.87. Critical value: t= - 1.711. Do not reject Ho. There is not sufficient evidence to conclude that the mean is less than 26.

You wish to determine the average VO2max (maximum rate of oxygen consumption, often associated with athletic performance) of a sample of 100 Olympic athletes, and to use a quantitative metric to assess your confidence in the average (mean) value. You calculate a mean of 71 ml/kg/min and a variance of 26.06 from your sample. Question: What are the standard error of the mean (SEM) and the approximate 95% CI of the mean?

Weights of one-year-old male German Shepherd dogs have a standard deviation of 1.5 lbs. Determine the percentage of all samples of 200 one-year-old male German Shepherds that have mean weights within 0.125 lb of the population mean weight of all one-year-old German Shepherds.
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.

Babies: A sample of 25 one-year-old girls had a mean weight of 24.1 pounds with a standard deviation of 4.3 pounds. Assume that the population of weights is normally distributed. A pediatrician claims that the standard deviation of the weights of one-year-old girls is greater than 7 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the =α0.05 level of significance.
