Score: 0 of 1 pt 90f 11 (3 complete) HW Score: 27.27%. 3 of 11 pts 6.1.33-T Question Help The probability distribution of the random variable X represents the number of hits a baseball player obtained in a game for the 2012 baseball season. X0.1679 The probability distribution was used along with statistical software to simulate 25 repettions of the experiment (25 games). The number of hilts was reoorded Approximate the mean and standard deviation of the random variable X based on the simulation. The simulation was repeated by performing 50 repetitions of the experiment. Approximate the mean and standard deviation of the random variable. Compare your results to the theoretical mean and standard deviation. What property is being illustrated? EE Click the icon to view the data tables Data Tables Incorrect: 0 Compute the theoretical mean of the random variable X for the given probability distribution #x=| |hits Round to three decimal places as needed.) Table of the numbers of hits for 25 games Table of the numbers of hits for 50 games Enter your answer in the answer box and then click Check Answer Print Done 7partaining Clear All

Explanation / Answer

Theoritical mean = 0*0.1679 + 1*0.3438 + 2*0.2824 + 3*0.1496 + 4*0.0367 + 5*0.0196

= 1.6022

=> x = 1.602 hits.
