Consider bit strings of length 10 in the following questions. a. How many bit strings begin with 1? Answer: b. How many bit strings begin with 1 or ends with 10? c. What is the probability that a bit string selected at random starts with 1? Show your answer in fraction form. Answer: d. What is the probability that a bit string selected at random ends with 10 and begins with 1? Show your answer in fraction form. Answer: e. What is the probability that a bit string selected at random ends with 10 given that the bit string begins with 1? Show your answer in fraction form. Answer:
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
