Many ground level plants in tropical rainforests have adapted to the shade of the forest canopy. These plants tend to function well as house plants since they require minimal sunlight. A botanist is interested in "domesticating" a particular plant found in the Amazon rainforest. The botanist wants to estimate the true proportion of this species of plant that will survive inside. Assuming an appropriate sample can be obtained, which confidence interval would be most appropriate for this task? A. One sample z-confidence interval, B. One sample t-confidence interval, C. Paired-samples t-confidence interval, D. Independent samples t-confidence interval, E. Confidence interval for one proportion, or Confidence interval for two proportions

Liam owns some rectangular plots of land. All of the plots are the same length, x, and the width of each plot is 5 yards less than the length. The total number of plots Liam owns is 20 more than the length of a plot. If the total area of all the plots Liam owns is 2,688 square yards, which statements about the length of each plot are true?*The equation x3 − 15x2 − 100x − 2,688 = 0 can be used to find the length of each plot.**The equation x3 + 25x2 + 100x − 2,688 = 0 can be used to find the length of each plot.***The equation x3 + 15x2 − 100x – 2,688 = 0 can be used to find the length of each plot.****The length of each plot is 12 yards.*****The length of each plot is 8 yards.
