.. Suppose r, s > 0 are interest rates. You invest in an account which compounds at the end of each month according to the following schedule: Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Rate r r r r (i) If you invest P dollars into this account on January 1st, and this is the only deposit that you make, what is the value of the account after one year? (ii) Suppose you invest P dollars on January 1st of every year. What is the value of the annuity after n-years? Express your answer without using a sum. (iii) Suppose you invest P dollars on January 1st, April 1st, July 1st, and October 1st of each year. What is the value of the annuity after n-years? Express your answer without using a sum.
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.
