In a university of wisconsin (uw) study about alcohol abuse among students, 100 of the 40,858 members of the student body in madison were sampled and asked to complete a questionnaire. one question asked was, "on how many days in the past week did you consume at least one alcoholic drink? " a. identify the population and the sample. b. for the 40,858 students at uw, one characteristic of interest was the percentage who would respond "zero" to this question. for the 100 students sampled, suppose 29% gave this response. does this mean that 29% of the entire population of uw students would make this response? explain.

a) The population is 40,858 students and the sample is 100.

b) No

Step-by-step explanation:

a) The population would be the 40,858 members of the student body. Since we are only applying the questionnaire to 100 students, the sample would be 100.

b) 29% of the students answered "zero" to the question on how many days in the past week they consumed at least one alcoholic drink. This means that 29 out of 100 students gave this answer. However, this doesn't mean that 29% of the entire population of UW would give this response. Why is that? Because our sample is very small so it might not be representative of the whole population. Equally, the results from such a sample cannot be exactly the same results we would get from an entire population.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

multiply each one by 3.14
