A sample of 77 subjects went on a low-carbohydrate diet for six months. At the end of that time, thesample mean weight loss was 4.7 kilograms with a sample standard deviation of 7.16 kilograms. A secondsample of 79 subjects went on a low-fat diet. Their sample mean weight loss was 2.6 kilograms with astandard deviation of 5.90 kilograms. Can you conclude that the mean weight loss differs between the twodiets? Use a = 0.01. Use the critical value method.

Given that Sample size n1=77 , n2=79 Sample means x1=4.7 , x2=2.6 s1=7.16 , s2=5.9

Low-fat or low-carb? Are low-fat diets or low-carb diets more effective for weight loss? A sample of 76 subjects went on a low-carbohydrate diet for six months. At the end of that time, the sample mean weight loss was 4.6 kilograms with a sample standard deviation of 7.07 kilograms. A second sample of 78 subjects went on a low-fat diet. Their sample mean weight loss was 2.6 kilograms with a standard deviation of 5.83 kilograms. Can you conclude that the mean weight loss of subjects having low-carb diets is greater than the mean weight loss of subjects having low-fat diets? Let u, denote the mean weight lost on the low-carb diet and ₂ denote the mean weight lost on the low-fat diet. Use the a= 0.01 level and the TI-84 Plus calculator.

The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of two English courses with a standard deviation of 0.8. The females took an average of three English courses with a standard deviation of 1.2. Are the means statistically the same? (Use ? = 0.05) NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) a. What is the P-value? Explain what the p-value means for this problem. b. Sketch a picture of the situation. Label and scale the horizontal axis and shad the region corresponding to the p-value c. Indicate rather we "reject" or "do not reject" the null hypothesis d. Explain how you determined which disticution to use

A student earned a 79 on a precalculus exam, and she earned a 92 on a statistics exam. The precalculus exam had a mean score of 72.3 with a standard deviation of 8.4. On the other hand, the statistics exam had a mean score of 87.4 with a standard deviation of 11.4. Determine which exam the student earned a better score on with respect to her peers.

A community college Math instructor feels that the average age of community college students decreased since they started teaching 25 years ago. Looking up data from the year the instructor started teaching, the mean age of community college students was 24.3 years old, with a population standard deviation of 2.2 years. The Math instructor took a sample of 40 of their current community college students and found that the sample had a mean age of 23.7 years old. Assume the population of ages of community college students is normally distributed and that the population standard deviation has remained the same. Test at the 5% significance level if the mean age of community college students is now less than 24.3 years old. Choose the correct answer from the parenthesis.
