Final answer:
The question appears to be mixing the concept of academic grades with Beta Sigma Phi's membership levels. With a 1 percent significance level, there was not sufficient evidence of different mean grades among sororities. Beta Sigma Phi degrees refer to levels of membership, not academic grades.
Step-by-step explanation:
The question 'How many degrees are there in Beta Sigma Phi?' appears to be a mix-up, possibly confusing academic grading with the structure of a sorority. When assessing whether there is a difference in mean grades among sororities, statistical tests are used. In the case mentioned, using a significance level of 1 percent, the conclusion was that there is not sufficient evidence to conclude that there is a difference among the mean grades for the sororities. Beta Sigma Phi is actually an international social, service, and cultural organization for women. The 'degrees' in this context refer to levels of membership or recognition within the organization, not academic grades. Traditionally, Beta Sigma Phi has different degrees of membership that members can progress through based on participation and tenure
