Question 2Suppose the school board wished to see whether the age of the student affecis test achievement. The Lesting caordinator separated the raster of high schoolStudents into freshmen, sophomores, juniors, and seniors and randomly selected 20 students from each classification. She then flipped a coin to determine whichtest format each student would receive and then compared the results as follows:• Freshmen who took the multiple-choice test compared to freshmen who took the fill-in-the blank exam• Muliple chaice saphomares compared to fill-in-the-blank saphomares• Muliple-chaice juniors compared ta fill-in-the blank juniors• Muliple chaice seniors compared to fill-in-the-blank seniors.Randomization still occurred because the testing coordinator flipped the coin to assign the test format to each student. This approach is an example of what typeof sampling technique?Your answer:O Simple random samplingO Stratified random samplingO Systematic samplingO Cluster samplingo Convenience sampling

The correct option is Stratified random sampling

A research center claims that 29% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 800 adults in that country, 31% say that they would travel into space on a commercial flight if they could afford it.

A telecommunication company proposed construction of a cell site tower in a certain city. To determine whether this is to be constructed, a vote is to be taken among the residents of a city and the surrounding barangays. Many residents in the barangays feel that the proposal will pass because of the large proportion of city voters who favor the construction. A poll is taken to determine if there is a significant difference in the proportion of city voters and barangay voters favoring the proposal. If 250 of 400 city voters favor the proposal and 360 of 500 barangay residents favor it, would you agree that the proportion of city voters favoring the proposal is higher than the proportion of barangay voters? Use a 0.025 level of significance.

Suppose you asked a sample of individuals if they are a Republican, Democrat, or Independent and also asked them for their opinion (for or against) on the death penalty. Is this a one-way Chi-square or a two-way Chi-square problem?
