A company, where the average yearly employee salary is 480.000NOK with a standard deviation of 15.000 NOK, offers you a job with 450.000NOK yearly salary. You can conclude that you will probably be earning less than a typical employee in the company

Two factor independent analysis of variance (Two-way ANOVA) is applied in a situation when a researcher analyzes the effect of the two independent variables on one dependent variable, and dependent variable is continuous.
A) True
B) False
A) True
A researcher was interested in the effects of hints on a person’s ability to solve anagrams. The time it took a participants to solve five eight-letter anagrams was measured. The same five anagrams were used in three conditions: first letter (where the first letter of the word was given), last letter (where the last letter was given), and no letter (where no help was given). Thirty participants were chosen and ten were randomly allocated to each condition. The number of minutes it took to solve the five anagrams was recorded. The researcher believes that One-way ANOVA is the appropriate test for this analysis.
A) True
B) False
A) True

A) True
B) False
A) True
The probability of an event is a numerical value that represents the proportion of times the event is expected to occur when the experiment is repeated under identical conditions.
A) True
B) False
A) True
What is the probabilty that a person who just turned 80 will survive beyond age 90? A researcher must apply ’conditional probability’ to answer this question.
A) True
B) False
A) True
On the basis of the mean values, given in the table (See the attached file), researcher can conclude that ’Service quality’ is the least important factor.
A) True
B) False
A) True
A low standard deviation means that the data is very closely related to the average, thus very reliable.
A) True
B) False
A) True
The figure in the attached file shows distributions for the two data sets. A researcher concluded that both data sets follow normal distribution.
A) True
B) False
B) False

A) True
B) False
A) True
A correlation is performed to test the degree to which the scores on the two variables correlate, that is the extent to which the variation in the scores on one variable results in a corresponding variation in the scores on the second variable.
