Below are the data from the study described in lecture about assessingwhether Beagles or German Shepherds Dogs dig more holes. Once again, mybuddy Mike hypothesizes that Beagles will dig more holes than Shepherds.Ten of each dog species are randomly assigned to fresh backyards. Mike goesto work and counts the number of holes dug in each yard when he getshome. As expected, one of the Beagles escaped, so that Beagle's score waseliminated from the data (i.e., n = 10 for the Shepherds, but n = 9 for the%3DBeagles). Go through the steps of hypothesis testing and evaluate Mike'shypothesis, using alpha = .05.BeaglesGSD|1271016481141H n ON

A city has 4 voting districts. Records from previous years show the proportion of registered voters that voted in previous elections for each district. A political analyst wants to see if those proportions have changed for this year's upcoming elections. The political analyst randomly samples 81 registered voters and asks them which district they live in and if they have voted yet. Ho: PA = 0.3; PB = 0.1; pc = 0.2; PD = 0.4 Test the claim that there is a difference in the proportions using a a= 0.05. Round all answers to at least 4 decimal places. a. Complete the table.

John Calipari, head basketball coach for the 2012 national champion University of Kentucky Wildcats, is the highest paid coach in college basketball with an annual salary of $5.4 million (USA Today, March 29, 2012). The sample below shows the head basketball coach's salary for a sample of 10 schools playing NCAA Division 1 basketball. Salary data are in millions of dollars. University Coach’s Salary University Coach’s Salary Indiana 2.2 Syracuse 1.5 Xavier .5 Murray State .2 Texas 2.4 Florida State 1.5 Connecticut 2.7 South Dakota State .1 West Virginia 2.0 Vermont .2 a. Use the sample mean for the 10 schools to estimate the population mean annual salary for head basketball coaches at colleges and universities playing NCAA Division 1 basketball (to 2 decimals). b. Use the data to estimate the population standard deviation for the annual salary for head basketball coaches (to 4 decimals).

A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. The data collected is reported in the table below. W-Mart Tag URToy 8 5 4 9 4 2 10 6 1 9 3 5 9 5 4 MW = 9 MT = 4.6 MU = 3.2 SSW = 2 SST = 5.2 SSU = 10.8 What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure? Compute the percentage of variance explained by the group differences for these data. Percentage and…
