In the previous problem, supposed that the researchers suspected that women over the age of 55 may respond differently to the treatment. Given that a random sample of 40,000 women over the age of 45 has already been chosen, the study would have been improved by:

a stratified sample, with strata determined by age.

a stratified sample, with strata determined by gender.

a block design, with blocks determined by age.

a block design, with blocks determined by gender.

a double-blind completely randomized design.

Left-handedness is the preference for the left hand over the right for everyday activities such as writing. Studies indicate that about 93% of the population may be characterized as right-handed. Researchers would like to conduct a study to determine if left-handed teens differ significantly in their ability to memorize facts than right-handed teens. Suppose the researchers concluded that the average number of words memorized by left-handed teens was statistically significantly higher than the average number memorized by right-handed teens. In this context, statistically significant means that:

the number of words memorized by left-handed students exceeded the number memorized by right-handed students.

the average number of words memorized by left-handed students exceeded the average number memorized by right-handed students.

right-handed students tend to not do as well as left-handed students in memorizing words.

it would be unlikely to observe an average difference as large as was observed by chance variation.

a randomized, controlled experiment was conducted.

A market research company wishes to find out whether the population of students at a university prefers Starbucks or Dunkin Donuts. A random sample of students is selected, and each student is asked first to try both but the order they try them is randomly decided with a coin toss (heads: Starbucks, then Dunkin. tails: vice versa). They then indicate which brand they prefer. This is an example of
