Answer:
The missing probability is, P (X = 7) = 0.24.
Step-by-step explanation:
The complete question is:
A psychology experiment on memory was conducted which required participants to recall anywhere from 1 to 10 pieces of information. Based on many results, the (partial) probability distribution below was determined for the discrete random variable (X = number of pieces of information remembered (during a fixed time period)).
What is the missing probability P(X=7)? Your answer should include the second decimal place.
X = # information | probability:
1 | 0.0
2 | 0.02
3 | 0.04
4 | 0.07
5 | 0.15
6 | 0.18
7 | ?
8 | 0.14
9 | 0.11
10 | 0.05
Solution:
The sum of the probabilities of all events of an experiment is always 1.
Use the above theorem to compute the missing probability.
Thus, the missing probability is, P (X = 7) = 0.24.
let n take values 1,2,3... infinity
then the sequence is:
(0,1/n)
for every number greater than zero there exist such n that (0,1/n) does not contain that number.

Step-by-step explanation:
Please find attached the diagram used in answering this question
A box plot is used to study the distribution and level of a set of scores
the scores are distributed into 4 groups. Each group has a value of 25%
the box plot consists of two lines and a box. the two lines are known as whiskers. the whiskers represent scores outside the middle 50%
On the box, the first line to the left represents the lower quartile. 25% of the score represents the lower quartile
the next line on the box represents the median. 50% of the score represents the median
The third line on the box represents the upper quartile. 75% of the scores represents the upper quartile
In this question, 68 is on the second line which represents the median. Thus 1/2 of the height are at least 68 inches
