2. We refer to a recent poll on Democratic candidates for the Presidential election 2020, among a random national sample of 1,003 adults. Results have an error margin of plus or minus 3.5 percentage points. In the poll, Joe Biden, Elizabeth Warren, and Bernie Sanders were answered to be an appropriate candidate by 27%, 21%, and 19%, respectively. Assume the level of significance, a = 5%. (a) Calculate the standard deviation of the sample. (25 pts) Note: Convert the results...

According to exit polls, the voting "gender gap" was 22 points in the 2016 House of Representatives election; that is, women voted for Democrats by 10 percentage points, and men voted for Republicans by 12 percentage points. Political scientists are curious to see if this gap holds- or increases- in 2018, but statisticians might be more interested in the processes behind exit polling and the rellabllity of thelr results. When conducting exit polls, pollsters will randomly select a certain number...

The results of a study showed that heterosexual women, during ovulation, were significantly better at correctly identifying the marriage status of a man from a photograph of his face than women who were not ovulating. Near ovulation, on average women correctly identified the marriage status of about 66% of the 100 men shown to them. Assume that the sample distribution for this study is unimodal and symmetric and that the samples are collected randomly. If this is the probability of...

3.5-total number of ways in which 4 balls can be selected out of
6 white and 9 black balls = 15P4 = 32760
Number of ways in which 4 balls can be selected where first 2
are white and last 2 black = 6P2*9P2 = 2160
Thus, required probability = 2160/32760 =
