(1 point) You are interested in finding out the mean number of customers entering a 24-hour convenience store every 10-minutes. You suspect this can be modeled by the Poisson distribution with a a mean of = 3.59 customers. You are to randomly pick n = 57 10-minute time frames, and observe the number of customers who enter the convenience store in each. After which, you are to average the 57 counts you have. That is, compute the value of X...

An engineer performed N= 20 tests to assess the load capacity of a new anchoring device. The measured load capacities are as follows (in kN): 11.0 20.0 24.0 13.0 16.0 24.0 18.0 7.0 20.0 22.0 17.0 18.0 28.0 27.0 20.0 15.0 12.0 11.0 31.0 28.0 After having assessed that the load capacity is normally distributed, the engineer wants to determine some statistics...

A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...

2)According to a 2009 Reader's Digest article, people throw away about 12% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 68 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.18? Note: You should keep at least 4 decimal places for any intermediate calculations you make to match wamap's approach and calculations. Answer = (Enter your answer as a number accurate...
