Exam 15: Nonparametric Methods: Goodness-Of-Fit Tests

A survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related to the distance between their home and the street. A randomly selected sample of 100 property owners was contacted and the results are shown next. What is the null hypothesis?

A recent study of the relationship between social activity and education for a sample of corporate executives showed the following results. The appropriate test statistic for the analysis is a(n) __________.

To determine if a set of ungrouped raw data is normally distributed, we can use _________.

A recent study of the relationship between social activity and education for a sample of corporate executives showed the following results. The degrees of freedom for the analysis are __________.

For any chi-square goodness-of-fit test, the number of degrees of freedom is found by ______.

The following table classifies 100 individuals using two variables, gender and college attended. What is this two-way classification called?

The claim that "male and female students at Coastal Carolina University prefer different parking lots on campus" is an example of a chi-square null hypothesis.

The chi-square distribution becomes more symmetrical as the ____________.

Six people have declared their intentions to run for a trustee seat in the next local election. A political poll is conducted during the campaign among 1,020 randomly sampled voters to determine if there is any clear preference among the voters. The responses are shown next. What is the expected frequency for each candidate?

We are interested in knowing if the following frequency distribution is normally distributed. The population mean and standard deviation of the data are 600 and 160, respectively. If the distribution was normally distributed, what is the probability that an observation would be a member of the "400 up to 600" class?

Which of the following statements is correct regarding the chi-square distribution?

Which chi-square distribution would be closest to a normal distribution?

A survey of property owners' opinions about a street-widening project was taken to determine if owners' opinions were related to the distance between their home and the street. A randomly selected sample of 100 property owners was contacted and the results are shown next. What is the expected frequency for people against the project and who have over 120 feet of property foot-frontage?

To test a hypothesis to verify that an observed frequency distribution data is normally distributed, the expected frequencies are _______________ distributed.

If we wanted to see if tossing a die (a cube with the sides numbered one through six) had an equal chance of showing each side or number, what statistical test should be applied?

If the significance level for an Anderson-Darling test for normality is 0.05 and the p-value is 0.001, the null hypothesis is rejected and we conclude that the data _________ normally distributed.

A recent study of the relationship between social activity and education for a sample of corporate executives showed the following results. Based on the analysis, what can be concluded?

To test if an observed frequency distribution with five classes is normally distributed, we compute probabilities for each class based on a(n) _________________.

To test a hypothesis that a frequency distribution for sample data is normally distributed, class limits are transformed using a ____________.

Three new colors have been proposed for the Jeep Grand Cherokee vehicle. They are silvered-blue, almond, and willow green. The null hypothesis for a goodness-of-fit test would be _______________.
