Suppose we want to know the mean number of shurikens thrown each night by ninjas in Konoha village. Getting this information from every ninja in the village would take forever. Instead, we randomly select 20 ninjas from the ninja school that is closest to us. a. Describe the statistic of interest in this survey b. The method used to obtain the sample of ninjas above is an example of which of the following (i) convenience sampling (ii) voluntary response sampling (iii) stratified random sample (iv) multi-stage sampling
Consider the information above and in question 1. It is conjectured that the mean number of people attending all 2017 Veterans Day celebrations is 145, and of interest is to test this conjecture versus the alternative that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people To test the hypothesis, a simple random sample of 41 Veterans Day celebrations was selected and the number of people attending each was recorded. The mean number of people attending for this sample of 41 celebrations was 157, with a standard deviation of 23 people. The distribution of the data was bimodal. If appropriate, use this information to test the hypotheses stated in question 3 at the a = .05 level of significance.

9. The GRE is a test that is widely used by many Universities throughout the country to determine graduate (Masters, Doctorate, Professional, etc) admissions. It consists of three parts: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing (Source: www.ets.org).

8. This question requires you to work z score problems with the sampling distribution of means. For each problem, begin by computing the standard error of the mean, using the formula: OM Then make two diagrams of the problem-one in terms of the actual scores, and one in terms of the z scores; mark the area under investigation on each curve. Show calculation of the appropriate z scores. List the line(s) from the z score table that you use to answer the question. Provide a verbal answer to each question. a. Assume you have a sampling distribution of means of samples of size n=16 from a population distribution in which u = 46 and o = 36. What proportion of sample means fall above M = 48? b.
