1. A researcher wants to determine the average given below.Describe how the researcher should apply the five basic steps in astatistical study. (Assume that all the people in the poll answeredtruthfully.) The average number of light bulbs per household thatfunction as designed. Determine how to apply the first basic stepin a statistical study in this situation. Choose the correct answerbelow. a. The population is all households. The researcher wants toestimate the average b. The population is all light bulbs thatfunction as designed. The researcher wants to estimate the averagenumber of light bulbs per household that function as designed. c.The population is all light bulbs that function as designed. Theresearcher wants to estimate the average number of light bulbs perhousehold that do not function as designed. d. The population isall households. The researcher wants to estimate the average numberof light bulbs per household that function as designed. 2.Determine how to apply the second basic step in a statistical studyin this situation. Choose the correct answer below. a. Theresearcher should gather data about functionality from the largestsample of light bulbs about whom the researcher can gather data. b.The researcher should only gather raw data from light bulbs thatfunction as designed. c. The researcher should gather raw data fromall light bulbs. d. The researcher should only gather raw data fromlight bulbs that do not function as designed. 3. Determine how toapply the third basic step in a statistical study in thissituation. Choose the correct answer below. a. The sample statisticof interest is the average number of light bulbs per household thatfunction as designed. b. The sample statistic of interests is theaverage number of light bulbs per household that do not function asdesigned. c. The sample statistic of interest is the percentage oflight bulbs that do not function as deigned. d. The samplestatistic of interest is the percentage of light bulbs thatfunction as designed. 4. Determine how to apply the fourth basicstep in a statistical study in this situation. Choose the correctanswer below. a. The researcher should use the sample statistic asan estimate for the population value of the average number of lightbulbs that function as designed and then use the methods ofstatistics to determine how good that estimate is. b. If thepercentage of light bulbs that function as designed in the sampleis greater than 50%, then the researcher can be confident that alllight bulbs function as designed. c. The sample statistic providesno useful information to the researcher in this situation. d. Ifthe researcher followed correct procedures, he or she can beconfident that the sample statistics is equal to the average numberof light bulbs that function as designed. 5. Determine how to applythe fifth basic step in a statistical study in this situation.Choose the correct answer below. a. The researcher should use themethods of statistics to determine the quality of the estimate ofthe population parameter and draw conclusions based on thisestimate accordingly. b. The researcher cannot draw any conclusionsbased on the value of the sample statistic. c. There is no way todetermine how well the sample statistic estimates the populationparameter. d. The researcher knows that the sample statistic isequal to the population parameter, so he or she may drawconclusions with complete confidence.
