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.

Suppose that we want to conduct a 98% confidence test about whether 2020 May
growing prices are higher than the historical average based on the data in exhibit 2.
Assuming that May 2020 growing prices are $7.30, which of the following best
represents the implications of this hypothesis test?
O while prices are higher in absolute terms, they do not represent a significant departure from
historical averages
we are moderately confident that prices are higher in 2020
O May 2020 prices are statistically lower than historical May prices
O we are 98% sure that prices are statistically higher than historical averages

FIND THE ANSWERS FOR B-2 and C. A survey found that Massachusetts residents spent an average of $861.75 on the lottery, more than three times the U.S. average.

A ✩ The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. 4466619/varlants/5145485/take/5/ 10 Length of Trout (inches) H 15 20 H 25 30 How many trout were less than 20 inches long? Hint: 20 inches is the upper quartile of the box-and- whisker plot. So, 75% of the trout were less than 20 inches long. To find the answer: multiply the percentage (75%) x 20 (the number of inches) We use 75% because that is the Q3 in the data. 25% would be our Q1 and 50% is the median (or Q2).
