Question

A tree farming company is testing how many items customers purchase during their visits. 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=6)? Note that the missing probability should be reported to the second decimal place.

Answer 1

Answer:

X probability = 0.02

Cumulative frequency at x ( 6 ) = 1

Step-by-step explanation:

X       P ( X )            Cf ( X )

1        0.58                0.58

2        0.18                0.58 + 0.18 = 0.76

3        0.10                0.76 + 0.10 = 0.86

4        0.07                0.86 + 0.07 = 0.93

5        0.05                0.93 + 0.05 = 0.98

6        0.02                0.98 + 0.02 = 1
