financial status: 1=over extended, 2=making ends meet, 3=comfortable

Expert Solution

One-way ANOVA: life satisfaction versus financial status

Method

Null hypothesis All means are equal
Alternative hypothesis At least one mean is different
Significance level α = 0.05

Equal variances were assumed for the analysis.

Factor Information

Factor Levels Values
financial status 3 1, 2, 3

Analysis of Variance

Source             DF Adj SS Adj MS F-Value P-Value
financial status    2   368.4 184.18    6.91    0.001
Error             179 4771.9   26.66
Total             181 5140.3

Model Summary

status      N    Mean StDev       95% CI
1          22   22.41   4.70 ( 20.24, 24.58)
2          90 25.744 5.713 (24.670, 26.818)
3          70 27.086 4.510 (25.868, 28.303)

Pooled StDev = 5.16322

F = 6.91

p-value= 0.001 < 0.05

hence we reject the null hypothesis

we conclude that there is difference in life satisfaction between different financial status

A group of researchers want to determine if there are any significant differences in life expectancy between smokers and nonsmokers. They test this question with a sample of 62 nonsmokers, where the average life expectancy was 78 years (SS = 2200), and a sample of 50 smokers, where the average life expectancy was 68 years (SS = 2300). Use a confidence interval (where α = .01) for the appropriate statistical test to determine if there is a significant difference in...

A. College Students’ Recent Life Experiences. Researchers administered to 216 undergraduate students (in the same time period) the Inventory of College Students’ Experiences and a measure of daily hassles. The total coefficient alpha was .92 for the Inventory and .96 for the measure of daily hassles. The Inventory correlated with daily hassles at .76 (p <. 001). B. Test scores for the Eysenck Personality Inventory and Cattell’s 16 Personality Factor Questionnaire (16PF) were obtained for male army applicants for flyer...

College administrators want to know if students would be willing to pay a new fee if most of it would be budgeted for Student Activities. A random sample of 632 students resulted in 516 that would be willing to pay the new fee. Construct a 90% Confidence Interval estimate for the proportion of students willing to pay the new fee.

Researchers want to know if playing violent video games increases aggression levels. They know that the typical teenager scores an average of μ = 4 on a test of aggression. To evaluate their hypothesis, they take a random sample of n = 5 teenagers and have them play violent video games for two hours. After playing the games the teenagers then are measured with the aggression test, resulting in the following scores: X 7 6 4 5 5 (a) Identify...

Researchers working for Kaiser want to know if there is a relationship between smoking and diabetes. They sample 900 patients at random from the population of patients who are 18 and older. In the sample, there are 145 smokers. Of these, 54 have no diabetes, 72 have pre-diabetes, and 19 have diabetes. Among the nonsmokers, 527 have no diabetes, 160 have pre-diabetes, and 68 have diabetes. (a) What is the null hypothesis the researchers might want to test, and what...

There are researchers who want to know if M poisoning in mice is less extreme in males. An SRS of one hundred male mice and an independent SRS of one hundred female mice are obtained. The male mice had a sample mean of thirty-nine and a sample standard deviation of eight. The female mice had a sample mean and standard deviation of 40 and 10, respectively. Let u1 represent the true mean response for the males and u2 represent the...

Researchers record the age and life satisfaction score (rated from 1 to 10, with higher scores indicating greater life satisfaction) among a sample of college students. They hypothesize that age will predict life satisfaction among college students. Compute an analysis of regression.

A team of researchers has developed a new weight loss supplement. They want to know if patients who use the new supplement for four weeks lose any weight. The supplement has some minor side effects including mild headaches and achiness. If the researchers obtain evidence of weight loss they will proceed to produce the supplement commercially and sell it for a large profit. If they do not obtain evidence of weight loss, the project will be ended. State the null...

To understand the implications of expanding health coverage, researchers want to know if people with health insurance use more health care than do people without it. To test this, they leveraged an administrative lottery that randomly assigned individuals to either receive public health care or not. Using the data below on the number of medical interactions (e.g., hospital visits or doctor appointments), test whether individuals with health insurance use health services differently than do those without it (alpha=0.1, two tails).No...

A team of researchers have developed a new weight loss drug. They want to know if patients who use the new drug for two weeks lose any weight. The drug has some minor side effects including mild headaches and achiness. If the researchers obtain evidence of weight loss they will proceed to produce the drug commercially and sell it for a large profit. If they do not obtain evidence of weight loss they will end the project. [70 points] What...
