Researchers were interested in determining whether weight is
associated with stress
levels. Conduct a One-way ANOVA to determine if weight and stress
are associated.
Assume, weight is normally distributed. unsure
a. State the null hypothesis.
b. State the alternative hypotheses.
c. What is the p-value?
d. What is the decision about the null hypothesis?
e. What type of error are you at risk for making?
f. Based upon the information generated, what can you say about the
association
between weight and stress?
Homework Answers
a. Null hypothesis: association of weight and stress is insignificant
b. Alternative hypothesis: association of weight and stress is significant
c. p-value is the probability that a test statistic assumes a value atleast as extreme as the one that was actually observed in the direction given by alternative hypothesis assuming null hypothesis to be true.
d. We reject null hypothesis if p-value is less than or equal to alpha, level of significance.

Independent Sample T-Test Researchers were interested in determining whether grounding techniques can decrease the length of panic attacks with people diagnosed with severe anxiety disorder. Subjects were randomly assigned into two different groups. Group 1 served as a control group, while Group 2 were taught various grounding techniques to manage their anxiety. Subjects were instructed to time their next panic attack and to record the length in minutes. Alpha (level of significance) was set at .05. State the null and...

Researchers were interested in whether there was a difference in physical activity (measured by average steps per day) between men and women. Activity monitors were handed out to 10 men and women and their daily steps were recorded for a week and then averaged out so that each individual had a daily average step count. Daily Steps Men (steps/day) Women (steps/day) X ± SD 6602.05 ± 1889.20 7397.62 ± 2037.05 df = 18 SE = 878.56 What are your null and...

An elementary school teacher is interested in determining if stress affects spelling performance. Ten students are randomly sampled for an experiment and randomly divided into two groups. One of the groups is subjected to moderate stress for two hours before the test while the other group stays for two hours in a relatively stress free environment. The teacher measures the number of correctly spelled words on a 30 item spelling test. The following data are obtained. Moderate Stress Condition :...

a-For over 25 years Fishy company has been selling canned sardines, mainly with a net weight of 425 grams. To your surprise, management has not tested the actual weight of the can in the last three years, and you wonder if the net weight of 425 grams is still appropriate. What would be the null and alternative hypothesis to test this? b- Say that Ho : µ ? 25.5 Ha : µ < 25.5 If n = 50, ? =...

4. The university is interested in determining if the proportion of graduates obtaining a first-class degree has changed from 2016 to 2017. Out of 2800 graduates in 2016, 560 obtained a first class degree. In 2017, 805 graduates out of 3500 obtained a first class degree. (a) Write down the method of moments estimates for the proportion of first-class degrees in 2016 and 2017, pˆ2016 and pˆ2017. (b) Write down appropriate null and alternative hypotheses for this test. (c) What...

9. A researcher is interested in whether child aggressive behavior changes after they see another child who has something that they want (but do not have). She devises an experiment where children come into her lab and are given worn and broken toys to play with. After a short time, another child is brought in the room and is given new, shiny toys to play with. The researcher wants to know whether there are changes in aggressive behavior among the...

The Canadian Real Estate Association is interested in determining if the average commission payed to the real estate agents has increased in the last ten years. Ten years ago, the average commission was 4%. A random sample of 25 commissions payed to real estate agents had an average of 4.75%. The population standard deviation is 1.36%. Does this indicate that the population average commission payed to real estate agents has increased? use a 5% level of significance. Assume x is...

On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on ? = 5 UAVs (all of the new type) resulting in a sample mean dwell time of ?1 = 10.4 h????. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10...

Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two independent test groups. The first group consisted of 14 people with the illness, and the second group consisted of 13 people with the illness. The first group received treatment 1 and had a mean time until remission of 172 days, with a standard deviation of 6 days. The second group received treatment and had a mean time until...

1. Fill out the following ANOVA table for the two-way ANOVA model. This table comes from a data set with 4 levels for factor A, 3 levels for factor B, and 14 values in each group. (Round your answer for F to two decimal places, your answers for SS and MS to one decimal place, and the p-value to three decimal places. Do not round any numbers until the final input into the answer box.) Analysis of Variance Source DF...
