The market share analysis company, Net Applications, monitors and reports on the use of the Internet browser. According to Net Applications, in the summer of 2014, Google's Chrome browser topped 20% of browsers for the first time, with a percentage of 20.37% (p = 0.2037). For a randomly selected group of 20 Internet browser users, answer the following questions. (In each case write a number. Where necessary, round to four decimal places. Include a zero before the decimal point in amounts less than 1). (d) For the sample of 20 users, calculate the variance ( ) and standard deviation for the number of Chrome users.

Develop a simulation using a TI-83/84 Plus calculator, STATDISK, Minitab, Excel, or any other suitable calculator or computer software program. Simulating Left-Handedness Refer to Exercise, which required a description of a simulation. a.Conduct the simulation and record the number of left-handed people. Is the percentage of left-handed people from the simulation reasonably close to the value of 10%? b. Repeat the simulation until it has been conducted a total of 10 times. Record the numbers of left-handed people in each case. Based on the results, would it be to randomly select 15 people and find that none of them is left-handed?
