### Job Satisfaction Survey AnalysisThe results of *Computerworld's* Annual Job Satisfaction Survey reveal insights into the satisfaction levels of information systems (IS) managers. The survey indicates:- 28% of IS managers are **very satisfied** with their job.- 46% are **somewhat satisfied**.- 12% are **neither satisfied nor dissatisfied**.- 10% are **somewhat dissatisfied**.- 4% are **very dissatisfied**.A sample of 500 computer programmers was also surveyed, yielding the following distribution of responses:| Category | Number of Respondents ||-------------------------|------------------------|| Very satisfied | 105 || Somewhat satisfied | 235 || Neither | 55 || Somewhat dissatisfied | 90 || Very dissatisfied | 15 |**Statistical Analysis**The objective is to determine whether the job satisfaction levels for computer programmers differ significantly from those of IS managers. A hypothesis test at a significance level of $ \alpha = 0.05 $ will be conducted to assess the differences in job satisfaction between the two groups. This involves comparing each category's percentage distribution between IS managers and the surveyed computer programmers.

Consider that pi’s are the proportion of respondents who are “very satisfied”, “Somewhat satisfied”,…

The results of Computerworld's Annual Job Satisfaction Survey showed that 28% of in- formation systems (IS) managers are very satisfied with their job, 46% are somewhat sat- isfied, 12% are neither satisfied nor dissatisfied, 10% are somewhat dissatisfied, and 4% are very dissatisfied. Suppose that a sample of 500 computer programmers yielded the following results. Number of Category Respondents Very satisfied Somewhat satisfied 105 235 55 90 Neither Somewhat dissatisfied Very dissatisfied 15 Use a = .05 and test to determine whether the job satisfaction for computer programmers is different from the job satisfaction for IS managers.

A researcher wants to see if police officers’ enthusiasm for their jobs changes after having endured a horrific event (such as killing someone or being shot). She tests a group of officers who have endured such an event and another group that has not on a measure of job satisfaction. What test should she run? Is it one-tailed or two-tailed test?
A researcher conducts an experiment to test whether memory changes with age. They recruited 24 participants separated into four age groups. The groups differ according to the age of subjects. In group one, all participants are 30 years old. Group 2, 40 years old. Group 3, 50 years old. And group 4, 60 years old. Assume that the participants are all in good health and that the groups are matched on other important variables such as years of education, IQ, gender, motivation, and so on. Each participant is shown a series of nonsense syllables ( a meaningless combination of three letters such as Daf or FUM ) at a rate of one syllable every four seconds. The series is shown twice, after which participants are asked to write down as many of the syllables as they can remember. Below is number of syllables remembered by each participant. 30 years old 14 13 15 17 12 10 40 years old 12 15 16 11 12 18 50 years old 17 14 14 9 13 15 60 years old 13 10 7 8 6 9 what is the alternative and null…
The following table shows the rank attained by male and female officers in the New York City Police Department (NYPD). Do these data indicate that men and women are equitably represented at all levels of the department? Test using a p-value approach. Male Female Officer 21,900 4281 Detective 4058 806 Sergeant 3898 415 Lieutenant 1333 89 Captain 359 12 Higher ranks 218 10 2. There are far more men than women in the police force in general. However, the NYC Police Commission has set itself certain goals with respect to the positions of the females among its ranks. Across the females they aim to target the same proportion by rank as they do among the males. The target proportions by category are: (1) Officer – 70% (2) Detectives – 15% (3) Sargent – 10% (4) Lieutenant – 3% (5) Captain – 1% (6) Higher – 1% Conduct a test to determine whether the proportions, by rank, among the…
A researcher is interested in the relationship between birth order and personality. A sample of n= 100 people is obtained, all of whom grew up in families as one of three children. Each person is given a personality test, and the researcher also records the person’s birth-order position (1st born, 2nd, or 3rd). The frequencies from this study are shown in the following table. On the basis of these data, can the researcher conclude that there is a significant relation between birth order and personality? Test at the .05 level of significance. Birth Position 1st 2nd 3rd Outgoing 13 31 16 Reserved 17 19 4 The expected frequencies for Outgoing, Birth Position 1st is: The expected frequencies for…
Medical researchers followed 6272 Swedish men for 30 years to see if there was any association between the amount of fish in their diet and prostate cancer. (“Fatty Fish Consumption and Risk of Prostate Cancer,” Lancet, June 2001). A summary of the data is given in the table below. Fish Consumption No Prostate Cancers Prostate Cancers Never/Seldom 110 14 Small part of diet 2420 201 Moderate part of diet 2769 209 Large part of diet 507 42 A) If a patient is randomly selected, what is the probability that he/she had prostate cancer given that fish was never or seldom a part of the diet? Round your answer to three decimal places and include the leading zero. B) If a patient is randomly selected, what is the probability that s/he ate fish as a large part of their diet given that they had prostate cancer. Round your answer to two decimal places and include the leading zero.
