Using the given histogram, we have that 90% of the players in the sample have scores that are less than 2300.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on a search engine, we have that the histogram states as follows:

  • 6 of these players have scores between 300 and 700.
  • 6 of these players have scores between 700 and 1100.
  • 13 of these players have scores between 1100 and 1500.
  • 14 of these players have scores between 1500 and 1900.
  • 6 of these players have scores between 1900 and 1300.
  • 5 of these players have scores between 2300 and 2700.

It asks the proportion of players in the sample with <u>scores that are less than 2300</u>.

<h3>What is an histogram?</h3>

An histogram is a graph that shows the <u>number of times each element of x was observed.</u>

Above, we already gave the amounts presented by histogram, and we have that 45 out of 50 players have <u>scores that are less than 2300</u>, hence the proportion is given by:

p = 45/50 = 0.9.
