Chapter 8, Problem 10 Aa Aa A random sample is selected from a normal population with a mean of u = 30 and a standard deviation of o = 8. After a treatment is administered to the individuals in the sample, the sample mean is found to be M = 33. If the sample consists of n = 16 scores, is the sample mean sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with a = .05. If needed, use the Standard Normal Distribution tool to help you find the critical value. Standard Normal Distribution Mean = 0,0 Standard Deviation = 1.0 .so0 1.5000, -2.0 0.0 1.0 2.0 0.0000 z-critical You conclude that the treatment has a significant effect. If the sample consists of n = 64 scores, is the sample mean sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with a = .05. z-critical You conclude that the treatment has a significant effect. Comparing your answers for the preceding parts, explain how the size of the sample influences the outcome ofa hypothesis test: A larger sample the likelihood of rejecting the null hypothesis.

Please complete the following question. Make sure you are responding to all parts of the question.    The number of awards earned by students at one high school is recorded.

Part D please

PLEASE ANSWER ALL PARTS OF THE QUESTION AND USE THE IMAGE FOR A GUIDE A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32.   The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment? Briefly explain your answer.     A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots.
