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.

Use a 1% level of significance to test if there is a difference in
the population mean hours per fish caught using a boat
compared with fishing from the shore. (Let d = B - A.)
(a) What is the level of significance?
State the null and alternate hypotheses. Will you use a left-
tailed, right-tailed, or two-tailed test?
Họ: ld = 0; H1: µd * 0; two-tailed
Ho: Hd # 0; H1: µd = 0; two-tailed
Ho: Hd = 0; H1: Hd < 0; left-tailed
Ho: Hd = 0; H1: Hd> 0; right-tailed
(b) What sampling distribution will you use? What
assumptions are you making?
The standard normal. We assume that d has an approximately normal distribution.
The Student's t. We assume that d has an approximately uniform distribution.
The Student's t. We assume that d has an approximately normal distribution.
The standard normal. We assume that d has an approximately uniform distribution.
What is the value of the sample test statistic? (Round your
answer to three decimal places.)
