Question

what does the null hypothesis (h₀) represent in this gender discrimination study? * 1 point
males are more likely to be promoted than females
promotion and gender are independent (no discrimination)
there is gender discrimination in promotion decisions
the observed difference is statistically significant
in the card simulation activity, why were exactly 13 face cards and 35 number cards used? * 1 point
to match the original study where 13 people were not promoted and 35 were promoted
to create equal groups of 24 cards each for males and females
to represent the 13 male and 35 female supervisors in the study
to ensure the simulation would show gender discrimination

Explanation:

1. In hypothesis - testing for discrimination, the null hypothesis typically represents no effect or no relationship. In the context of gender discrimination in promotion, it means promotion and gender are independent.
2. In the card - simulation activity, the number of face and number cards is likely related to the real - world situation being modeled. If 13 people were not promoted and 35 were promoted in the original study, using 13 face cards and 35 number cards can simulate this situation.

Answer:

1. Promotion and gender are independent (no discrimination)
2. To match the original study where 13 people were not promoted and 35 were promoted
