The probability that Julie will make a free throw is 40 percent what is the probability that she will make 4 out of her next 6 free throw shots?

The probability of four out of six shots is the probability of four successes, times the probability of two failures, times the number of permutations of successes and failures: P(four out of six free throws) = 15 * (2/5)4 * (3/5)2 = (15 * 16 * 9) / (625 * 25) = 432 / 3125


Three quarters of the students are or is?

It depends on the context. If the students are acting individually, then "are" is correct: Three-quarters of the students are failing the class. If you are referring to a single collective entity then "is" is correct: Three quarters of the students is an unacceptable number of failures.


What is proportions test?

Many researchers use a proportions test to verify the statistically significant difference between two independent proportions. This test has a number of requirements such as the use of random sampling, samples must be independent, at least 10 successes and 10 failures, and the population is at least 10 times the size of the sample.


Who developed the Causal Dimension Scale II?

The Causal Dimension Scale II was developed by researchers Mark R. Levesque and David R. McAuley. It is designed to measure individuals' perceptions of the causes of their successes and failures across various domains. The scale assesses dimensions such as locus of causality, stability, and controllability, providing insights into motivational processes.


In statistics what is Pi used for?

In statistics, pi represents the population proportion of successes. Using p, the sample proportion of successes, inferences can be made about pi, although it is usually unknown.
