A researcher wanted to compare the final test scores of students who used two different types of study materials. The researcher randomly selected two samples of 20 students using each type of material and determined the final test score of each student. The table shows the mean final score and the mean absolute deviation (MAD) for each sample. Study material Mean (%) MAD 1 94 5 2 90 2 Calculate the means-to-MAD ratio. Can the researcher conclude that Material 1 leads to higher final test scores? Select from the drop-down menus to correctly answer the question. The researcher conclude that Material 1 leads to higher final test scores because the distributions of the scores in the two samples are .

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
