The Novaco Provocation Inventory (NPI) is either an 80 or 90 item instrument for assessing anger responsiveness. (in order to maximize the variability, the 90-item version was used in this study) The test consists of brief descriptions of situations of provocation, for which the respondent notes the degree of anger that he/she might experience if that event should occur in his/her life. The ratings are on a 5-point Likert-type scale. The main purpose of the NPl is to gauge the range and intensity of a person's anger. Three groups of inmates from a state prison were selected and grouped on the basis of whether this was a first incarceration, a second incarceration, or a third incarceration. Each man took the NPl and the results were as follows: First Second Third

Test the hypothesis that anger is a function of the number of incarcerations. If the F is significant, follow it with a Tukey. If the Levene’s test is violated, simply indicate it is untenable and proceed with the analysis.

Determine the mean and variance of the random variable with the following probability mass function. f(x)=( 729divided by 91) (1 divided by 9) superscript x baseline comma x equals 1,2,3 round your answers to three decimal places (e.g. 98.765).

The price of an item has been reduced by 30%. the original price was $30. what is the price of the item now ?

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
