Did I Get This – Point Estimation
A psychology researcher was conducting a study about newlywed heterosexual couples during the first two years of their marriage. 513 newlywed couples were randomly chosen for the study. One of the questions that the researcher was interested in was “During a typical week, how many times do you have sex?” The 513 responses had an average of 2.35 and standard deviation of 1.2. Another question that was asked is “During a typical week, how many evenings do you go out?” 171 of the couples answered that they go out more than twice a week.
