State whether each situation has independent or paired (dependent) samples. a. A researcher wants to know whether men and women at a particular office have different mean credit ratings. She gathers two random samples (one of credit ratings from 50 men and the other from 50 women.) b. A researcher wants to know whether couples have different mean credit ratings. He collects a sample of couples and has each person report his or her credit rating. a. Choose the correct answer below. O Paired (dependent) samples O Independent samples b. Choose the correct answer below. Paired (dependent) samples O Independent samples

Using data from a national health survey, researchers looked at the pulse rate for nearly 800 people to see whether it is plausible that men and women have the same population mean. The data are random and independent. Technology output is shown in the accompanying table. Complete parts (a) through (c) below. Click the icon to view the technology output. a. Are the conditions for using a confidence interval for the difference between two means met? Select all that apply. A. Yes, all conditions are met. B. No, the Large Samples condition does not hold. C. No, the Independent Samples condition does not hold. D. No, the Random Samples and Independence condition does not hold. b. State the interval in a clear and correct sentence. Complete the sentence below. that the in pulse rate (women minus men) is between and beats per minute. (Type integers or decimals. Do not round. Use ascending order.) c. Does the interval capture 0? Explain what that shows. The interval for the difference 0. This implies that it plausible that
