Management at Scrooge McDuck National Bank knows that last year .5 of their employees requested to take their vacation in the summer, .2 in the spring, .2 in the fall, and .1 in the winter. They wonder if it will be the same this year. They run a multinomial test of proportions and are able to reject the null hypothesis. What do they now know?

There is not enough information to determine anything.

There is no season in which the majority of employees will request vacation.

The largest proportion of employees will request vacation time in the summer.

Employee vacation requests by season will be different than last year.
