Research questions:

RQ1
Is there a relationship between safety procedures and the willingness to buy a ticket for a space trip? H0: There is no relationship between safety procedures and the willingness to buy a ticket for a space trip HA: There is a relationship between safety procedures and the willingness to buy a ticket for a space trip

Dependent variable:willingness to buy ( interval
Independent variable:safety procedures ( nominal
Test: Independent Sample T-test

Survey Questions (2 and 3):

I am willing to buy a ticket for a space trip.

I think safety procedures are very important for space trips

With Research question 1 John Doe wants to test whether there is a relationship between the safety procedures, and therefor how safe people are feeling when they go aboard the space shuttle, and their willingness to buy a ticket for a space trip. When people know there are very much safety procedures, they can feel much more safe since they know everything is thought about and everything is checked. Going to space can be very dangerous as we have seen in the past 50 years, a lot of shuttle are crashed or got damage when they were up in space ( for instance space shuttle Colombia in 2003). People don’t want to risk their lives, when they get the indication that the space trip is professional and safe, they perhaps are much more willing to buy a space ticket. Thus the expected results for this test would be that there is a significant relationship between safety procedures and the willingness to buy a ticket. To get the right data, we make us of survey questions 2 and 3. The data for survey question 2 is nominal. The answers that could be given by the respondents are ‘yes’ and ‘no’. The data about willingness to buy a ticket we get from survey question 3. This data is given as an interval ratio, respondent could give answers like ‘totally agree’ ‘agree’ until ‘totally disagree’. Willingness to buy a ticket is the dependent variable and safety procedures are the independent variable. Therefor we make use of the independent sample t-test. To make use of the independent sample t-test there should be some condition fulfilled. The first condition is that respondent from each group should be with at least 30 persons. In our test this condition is not fulfilled since only 28 persons gave the answer ‘yes’ to survey question 2. Since it is not possible to recode this question, are test results are not reliable and should be treated with the knowledge that it is not fulfilling the requirements. The second condition is the Levene’s test. This test checks the variances of the two groups. The output of the Levene’s test is significant at 0,05 Alpha and therefore we can reject the hypothesis that the variances are equal. The last condition we have to check is the t-test for equality of means. This is less than 0,001 and therefor significant. This means that there is a relationship between safety procedures and willingness to buy. The people which disagree with safety procedures being important are not willing to buy tickets (2,0229) while the people which think safety procedures are important are between ‘agree’ willing to buy a ticket and ‘neither agree nor disagree’ willing to buy a ticket (3,1786). This outcome shows Virgin Galactic that safety is a very important feature for people when going on a space trip. Virgin Galactic is now able to influence their safety procedures and therefor to get more willingness to buy from consumers.

The fact that the tests were taking with a to small response from people which answered ‘yes’ to the statement about safety, should not be forgotten and should be taken in consideration while interpreting the results. We would increase the sample size next time.
