The null hypothesis: ∪ = 0; they do not grow after conversation
the alternative hypothesis : ∪ ≠ 0; they grow after conversation
Based on the question asked and the results given which is:
Based on the t-test statistic and p-value, researchers found moderate evidence against the null hypothesis. Give the final statement of the hypothesis test.
we can then draw a conclusion that: There is not enough evidence to conclude the mean difference in the height of the plants between the conversion and control groups is 0
Answer:
it shoud be 22.46
Step-by-step explanation:
Benchmark are numbers that are used as standards to which the rest of the data is compared to. When counting numbers using a number line, the benchmark numbers are the intervals written on the axis. For benchmark numbers of 10, the number line on top of the attached picture is shown. Starting from 170, the tick marks are added by 10, such that the next numbers are 180, 190, 200, and so on and so forth. When you want to find 410, just find the benchmark number 410.
The same applies to benchmark numbers in intervals of 100. If you want to find 170, used the benchmark numbers 100 and 200. Then, you estimate at which point represents 170. For 410, you base on the benchmark numbers 400 and 500.
