Big Burger is a fast food restaurant that has 450 locations all over the U.S. Use the excel output above to answer the following question.

Question:
What is the probability a selected restaurant is in a city with a population size between 50,000 and 100,000?

Expert Solution

Given That :

Region 1 = North West (NW)	Population 1 = Under 50,000
Region 2 = south West (SW)	Population 2 = 50,000 - 100,000
Region 3 = North East (NE)	Population 3 = Over 100,000
Region 4 = South east (SE) probability of a selected restaurant is in a city with a population size between 50,000 and 100,000 Number of restaurants in city and population size under 50,000 to 100,000 is = 36 + 36 + 44 = 147 Total number of restaurants = 450 The probability a selected restaurants is in a city with a population size under 50,000 to 100,000 is = 147/450 = 0.3266 The probability a selected restaurants is in a city with a population size under 50,000 to 100,000 is 0.3266.

Is the difference between the mean annual salaries of statisticians in Region 1 and Region 2 more than $8000? To decide, you select a random sample of statisticians from each region. The results of each survey are shown to the right. At α=0.10, what should you conclude? Answer A-E Region 1 x1 = $68,300 standard deviation = $8,750 n1 = 47 Region 2 x2 = $63,000 standard deviation = $9,275 n2 = 40 A. What are the alternative and null...

#2). Under-coverage is a problem that occurs in surveys when some groups in the population are underrepresented in the sampling frame used to select the sample. We can check for under-coverage by comparing the sample with known facts about the population. a. Suppose we take a SRS of n=500 people from a population that is 25% Hispanic. How many Hispanics are expected in a given sample? [2 points] b. What is the standard deviation for the number of Hispanics in...
