Choose all that are correct. 1. Random samples from the same population will vary from sample to sample.

2. as the sample size increases, the sample distribution more closely resembles the population distribution.

3. vallues of a sample statistic of different random samples of the same size from the same population will be the same

4. if a random sample is chosen from a population with a large cluster of points at the maixmum, the sample is likely to have at least one element neat the maximum

Choose the correct slope of the line that passes through the points (1, -3) and (3, -5)

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels.ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
