Baldur is very interested in statistics and spinning and he decided to combine these two interests and carry out the following research. He randomly selected 100 Reykjavik residents and asked them two questions. On the one hand whether they want chocolate, ice cream or caramel on their pacifier and on the other hand what gender they are. Questions 4-6 deal with Baldur's survey. Baldur's question: "What do you want most on your spinner?" Has three possible answers:1) chocolate, 2) ice cream, 3) caramel, What type is the variable that Baldur records? 1. Continuous category variables. 2. Continuous number variables. 3. Unordered category variables. 4. Sorted category variables. Baldur is interested in investigating whether there is a connection between the two variables, gender and what people want on their spinner. What kind of hypothesis test should Baldur use? 1. Ki-square test. 2. Hypothesis test for two averages. 3. Variance analysis. 4. Simple linear regression. Assume that the criteria that need to apply to perform the test that Baldur is to perform meet. Baldur is slippery in R and therefore performs the hypothesis test with the help of R and gets a p-value of 0.0002. What conclusion does Baldur draw if he uses the probability of error a = 0.05? 1. The proportion of men and women varies depending on what they want on their spinner. 2. At least one average is different from the others. 3. He does not draw any conclusions. 4. There is a relationship between gender and what people want on their spinner.

Question
Transcribed Image Text:Baldur is very interested in statistics and spinning and he decided to combine these two
interests and carry out the following research. He randomly selected 100 Reykjavik residents
and asked them two questions. On the one hand whether they want chocolate, ice cream or
caramel on their pacifier and on the other hand what gender they are. Questions 4-6 deal with
Baldur's survey.
Baldur's question: "What do you want most on your spinner?" Has three possible answers:1)
chocolate, 2) ice cream, 3) caramel, What type is the variable that Baldur records?
1. Continuous category variables.
2. Continuous number variables.
3. Unordered category variables.
4. Sorted category variables.
Baldur is interested in investigating whether there is a connection between the two variables,
gender and what people want on their spinner. What kind of hypothesis test should Baldur
use?
1. Ki-square test.
2. Hypothesis test for two averages.
3. Variance analysis.
4. Simple linear regression.
Assume that the criteria that need to apply to perform the test that Baldur is to perform meet.
Baldur is slippery in R and therefore performs the hypothesis test with the help of R and gets
a p-value of 0.0002. What conclusion does Baldur draw if he uses the probability of error a =
0.05?
1. The proportion of men and women varies depending on what they want on their spinner.
2. At least one average is different from the others.
3. He does not draw any conclusions.
4. There is a relationship between gender and what people want on their spinner.
