Question 48 - If a study has an alpha of 0.05 and a power of 0.80 you know the chance of making a type II error is:

	80%
	20%
	5%
	Unable to determine

Expert Solution

P(Type II error) = 1 - Power

= 1 - 0.80

= 0.20 = 20%

Option - B) 20%

What effect on power will more alternatives have? Question 48 options: It will decrease power Alternatives have no effect on power It will cause power to continuously fluctuate (unstable) It will increase power Question 49 (1 point) Two individuals are often in conflict in your workplace: Person A who is 22 years old and Person B who is 63 years old. How could you potentially categorize the source of their conflict? Question 49 options: Interdependence There is no source Differentiation...

alpha value is 0.05 if it is not specified in the problem. **Everything should be in r code base. 4. Back to the iris dataset one last time! We wish to estimate the probability of a flower’s species based on the available measurements. a. Build a Multinomial model to predict Species based on Sepal.Length. Use it to estimate the probability of each species for a flower with a sepal 6.3 cm long. b. Build a Multinomial model to predict Species...

Assume that you plan to use a significance level of alpha = 0.05 to test the claim that p1 = p2. Use the given sample sizes and numbers of successes to find the z test statistic for the hypothesis test. A report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized and 20 out of 208 without pet dogs were burglarized.

Produce the following for each problem: Assuming an Alpha = 0.05, calculate the number of replications necessary for each factor (including interactions), to have a type II error less or equal to 0.1. Evaluate results and provide conclusion(s). Scan the solutions to these problems.

I have calculated a probability of type two error at alpha 0.1 as 0.05730834612602564 and 0.05 as 0.11282997108101914. From these values how would i conclude the sampling method is good enough to reduce the effort(in my problem statement) How should i interpret the value of chi square test, where the result is statistic=15.066337549525954, pvalue=0.019746985983350823

Use alpha = 0.05 for hypothesis testing unless specified otherwise. 2. A college teacher decided to do an experiment to see whether the position her students satin the classroom had an effect on their performance in the class. At the beginning of the semester, she randomly assigned each student to one of three classroom positions: Front,Middle, or Back. As it turned out, 10 students were assigned to the Front of the room, 14students to the Middle, and 10 to the...
