a. Explanation Given info: A survey shows that 38% of managers hiring the employees were having a negative view of their workers with a messy desk. A random sample of 10 hiring managers was taken and was asked whether they had a negative view of their workers with a messy desk. The random variable x represents the number of hiring managers who have a negative view of workers with a messy desk. Calculation: Define the random variable x as the number of hiring managers who have a negative view of workers with a messy desk. Here, the total number of managers ( n ) is 10 and the managers are independent of each other. Also, there are two possible outcomes (having a negative view of their workers with a messy desk or not having a negative view of their workers with a messy desk) and the probability of the selected hiring manager who has a negative view of workers with a messy desk is ( p ) 0.38. Thus, x follows the binomial distribution. The binomial distribution formula is as follows: P ( x ) = n ! ( n − x ) ! x ! p x q n − x Where, n is the number of trials, x is the number of successes among n trials, p is the probability of success and q is the probability of failure b. To determine To graph: The binomial distribution using a histogram. To describe: The shape of the histogram. c. To determine To identify: The unusual values taken by the random variable x .

Information for questions 4 • • Please Download "wages" from Canvas (the link to this dataset is right below the HWA1 questions - it is a Microsoft excel worksheet) and store it in your favorite folder. It contains 797 observations and 16 variables. The "state" variable gives the names of the states involved in this dataset. • You need to have excel on your computer to open this dataset. i. You should use File > Import > Excel Spreadsheet etc. as done in class 3 convert this file into a Stata dataset. Once you are done, write the final STATA code that makes the transformation of an excel file to a STATA file possible. ii. Write a code that will close the log file that has been open since Question 1 part ii.
