Answer the following questions:

Q5:

Determine whether the samples are independent or dependent. A data set includes the height of 90 college students and 90 teachers. Choose the correct answer below. 0 A. The samples are independent because there is a natural pairing between the two samples. 0 B. The samples are independent because there is not a natural pairing between the two samples. 0 C. The samples are dependent because there is a natural pairing between the two samples. 0 D. The samples are dependent because there is not a natural pairing between the two samples. c. Express the confidence interval with measures from men being population 1 and measures from women being population 2. Choose the correct answer below. O A. - 1.76 g/ dL

. If one wants to use a condence interval to test the claim that \"d > 0 with a 0.01 signicance level, the condence interval should have a condence level of 98%. Listed below are body temperatures from ve different subjects measured at 8 AM and again at 12 AM. Find the values ofd and sd. In general, what does pd represent? Temperature (F) at 8 AM 97.7 98.9 97.1 97.8 97.1 % Temperature (F) at 12 AM 98.4 99.6 97.3 97.6 97.3 Let the temperature at 8AM be the rst sample, and the temperature at 12 AM he the second sample. Find the values of d and 5d. d = (Type an integer or a decimal. Do not round.) 5:: = (Round to two decimal places as needed.) In general, what does pd represent? 0 A. The mean of the differences from the population of matched data 0 B. The difference of the population means of the two populations 0 C. The mean of the means of each matched pair from the population of matched data 0 D. The mean value of the differences for the paired sample data
