alternate hypothesis (4.5,19,>19 or <19)
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.
The price-to-earning (P/E) ratio is an important tool in financial work. A random sample of 14 U.S. banks gave the followingP/E ratios: 24,16,22,14,12,13,17,22,15,19,23,13,11,18. The sample
- what is the null hypothesis ( 17.1,19,<17.1 or <19)
-what is the alternate hypothesis (4.5,19,>19 or <19)
-When conducting the hypothesis test a P-value of .0233 was calculated. With a significance level(α)of .05, should the null hypothesis be rejected,or does it fail to reject
