Leewood Middle School is considering a uniform policy, and the principal has asked for students' opinions about the colors for the uniform shirts. Jennifer and Josef conducted surveys about the possible shirt colors.
Their methods and results are described below. Jennifer Sampling method: Gave each student in her
history class a survey to complete anonymously at home and return the following day. She received 50% of
the surveys the next day. Results: 85% prefer blue shirts. Josef Sampling method: Wrote all students'
names on slips of paper. Gave survey to the 50 students whose names were chosen at random. Results:
60% prefer blue shirts.
Explain whose sampling method will provide results most representative of all students at Leewood Middle
School and why
Provide your own example of another method that would represent all students at Leewood Middle School.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
