Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The manager of a local bank observes how long it takes a customer to complete his transactions at the automatic bank teller machine (ATM).

1) Describe an appropriate sample space for this experiment.

a. {t | t < 0}

b.{t | t > 0}

c. {t | t = 0}

2) Describe the event that it takes a customer between 2 and 3 min to complete his transactions at the ATM.

a. {t | 2 ≤ t ≤ 3}

b. {t | t ≤ 2}

c. {t | t > 0}

d. {t | t ≤ 3}

e. {t | t > 2}

Definition Definition For any random event or experiment, the set that is formed with all the possible outcomes is called a sample space. When any random event takes place that has multiple outcomes, the possible outcomes are grouped together in a set. The sample space can be anything, from a set of vectors to real numbers.
